The Influence of Noise Level on the Stress Response of Hospitalized Cats

The study aimed to investigate the impact of noise levels in the hospital environment on the stress experienced by hospitalized cats undergoing elective ovariohysterectomy surgery. A total of 33 domestic female cats were included in the study, divided into four groups: a control group (CG) and three experimental groups based on ward noise levels: G1 (Quiet, <60 dB), G2 (Medium, between 60 and 85 dB), and G3 (Noisy, >85 dB). Behavioral assessments, respiratory rate (RR), and plasma cortisol levels ([Cort]p) were measured as indicators of stress. A composite measure of stress, termed the final stress value (FSV), was calculated by summing scores across various behavioral categories. Data collection occurred at three time points: immediately following surgery (T1), and at 2 h (T2) and 3 h (T3) post-surgery. FSV and RR were assessed at all three time points (T1, T2, and T3), while [Cort]p levels were measured at T1 and T3. The study observed that the median values of FSV, RR, and [Cort]p tended to increase with both higher noise levels and longer exposure durations to noise. Significant differences in RR were found between group pairs G1G2 at T1 (|D| = 0.63 < cut-off = 0.98), and G2G3 at T2 (|D| = 0.69 < cut-off = 0.97). Regarding [Cort]p, significant differences were noted between the CGG1 group pair at T0 (p < 0.01), and T3 (p = 0.03). Furthermore, an excellent Spearman correlation coefficient (rho = 0.91) was found between FSV and RR, indicating that RR can serve as an effective tool for assessing stress levels in cats. The findings of this study provide valuable insights into the welfare of cats in a hospital environment and support the scientific validity of existing recommendations aimed at improving their well-being. Specifically, the study underscores the importance of minimizing noise levels in hospitals as a means to reduce stress in cats. This conclusion aligns with existing guidelines and recommendations for enhancing the welfare of hospitalized cats.

Impact of stress on the tear production of healthy cats

OBJECTIVES

This study aimed to determine the impact of acute stress on tear production in companion cats to provide a basis for minimizing stress-inducing stimuli during ophthalmic evaluations.

METHODS

A total of 24 healthy owned cats (12 males, 12 females) of mixed breed, aged 8 months to 7 years, with no history of ocular diseases, were selected for the study. The cats were housed in individual cages under controlled conditions for 6 days. The Schirmer tear test-1 (STT-1) was performed in the morning (between 9:00 am and 11:00 am) using test strips from the same batch. The first test (without stress) was conducted on the fifth day of acclimation, and the second test (with stress) on the sixth day. The stress stimulus consisted of recordings of barking dogs, cats fighting and the murmuring of people. For both tests, the heart rate was assessed with a stethoscope before, during and after the tests, and the environmental stress level was also evaluated. Results are presented as mean ± SD and 95% confidence interval (CI).

RESULTS

The study found that STT-1 values were significantly higher (P = 0.009) with stress (22.2 ± 6.0 mm/min [95% CI 19.9-24.6]) than without stress (17.5 ± 6.9 mm/min [95% CI 14.8-20.2]). Similarly, the heart rate was significantly higher (P = 0.028) in stress vs non-stress conditions (213.4 ± 37.5 beats per minute [bpm] [95% CI 198.7-228.1] vs 171.5 ± 28.6 bpm [95% CI 160.3-182.7], respectively), and the environmental stress score was significantly higher (P <0.001) in stress vs non-stress conditions (3.3 ± 0.5 [95% CI 3.1-3.5] vs 1.2 ± 0.4 [95% CI 1.1-1.4], respectively).

CONCLUSIONS AND RELEVANCE

Stress increased tear production in cats. Although the mean STT-1 value obtained under stress conditions was within the normal range, stress can influence the test results. The use of cat friendly handling techniques facilitates execution of the STT-1.

Owner Perspectives of Cat Handling Techniques Used in the Veterinary Clinic

An online cross-sectional survey was used to assess cat owner attitudes towards 12 cat handling techniques used during veterinary appointments. Likert-scale questions were designed to assess level of agreement with handling techniques when the participants' cat is calm, fearful, or aggressive. We examined the influence of participant's cat attachment and demographic information on agreement towards common handling techniques. Overall, participants (n = 1754) disagreed with higher restraint techniques such as full body with scruffing, and agreed with lower restraint methods such as minimal restraint and use of towels, regardless of cat demeanor. Logistic regression models revealed that participants were more likely to disagree with the use of full body restraint with scruff on fearful cats if they had a higher pet attachment score (p = 0.002), were residents of the US (p = 0.003), or were between the ages of 51-70 years of age (p = 0.001). Owner agreement with techniques involving a lower degree of restraint during routine veterinary procedures provides further support for current recommendations encouraging handlers to use these techniques with cats, and to avoid methods requiring a higher degree of restraint.

Advice on cat behavior in German veterinary practices:Expectations of cat owners and influencing factors on compliance

Veterinarians play an important role in establishing and sharing the welfare of companion animals by carrying out regular health checks and informing owners about the specific needs of the animal's environment and conditions of good husbandry. A survey among German cat owners revealed which role advice about cat behavior plays in daily practice and its influence on the cat owner's compliance. Some owners (29.6%, n = 263/889) reported behavioral problems in their cat.  Not all owners considered their veterinarian as their contact of choice for behavioral advice, although veterinarians who met owners' expectations for advice on cat behavior are significantly more often described as feline-friendly (P < 0.000). Owners who expected an empathetic treatment of their cat will show a better compliance (P = 0.003). Owner compliance can be improved by providing accurate and effective veterinary advice about cat behavior and behavioral problems (P = 0.003). Thus, a sound foundation in cat behavior and knowledge of current treatment recommendations for feline behavioral problems can be worthwhile to ensure good husbandry for cats.

A Comparison of the Intrarectal and Intramuscular Effects of a Dexmedetomidine, Ketamine and Midazolam Mixture on Tear Production in Cats: A Randomized Controlled Trial

Cats are often easily stressed and uncooperative. The use of sedative agents in the feline species is widely used to perform even minor clinical and diagnostic procedures. The aim of this study is to assess the impact on tear film production of the intrarectal route (IR) administration of a mixture of dexmedetomidine, ketamine and midazolam in comparison with the intramuscular (IM) one. A group of twenty cats were involved in a randomized and blinded clinical trial. A clinical and ophthalmological examination was conducted on the cats. The IR group received dexmedetomidine 0.003 mg kg-1, ketamine 4 mg kg-1 and midazolam 0.4 mg kg-1; the IM group received dexmedetomidine 0.003 mg kg-1, ketamine 2 mg kg-1 and midazolam 0.2 mg kg-1. A Shirmer tear test I (STT- I) was conducted 1 h before sedation and 2', 10', 20', 30', 40', and 80' post drug administration. The reaction to STT-I administration was also evaluated. The IM group has a lower mean tear production than the IR group for all time points evaluated. Cats in the IM group showed less reaction to STT-I administration. This study may suggest that the effect of sedative agents administered by the IR route has a lower incidence on tear production than the IM one. The use of eye lubricant is recommended in any case.

Construct validity, responsiveness and reliability of the Feline Grimace Scale in kittens

OBJECTIVES

The aim of the present study was to investigate the construct validity, responsiveness and reliability of the Feline Grimace Scale (FGS) in kittens.

METHODS

A total of 36 healthy female kittens (aged 10 weeks to 6 months) were included in a prospective, randomized, blinded study. Video recordings of all kittens were made before and 1 and 2 h after ovariohysterectomy using an opioid-free injectable anesthetic protocol with or without multimodal analgesia. Additional recordings were taken before and 1 h after administration of rescue analgesia (buprenorphine 0.02 mg/kg IM) to painful kittens. Screenshots of facial images were collected from the video recordings for FGS scoring. Four observers blinded to treatment groups and time points scored 111 randomized images twice with a 5-week interval using the FGS. Five action units (AUs) were scored (ear position, orbital tightening, muzzle tension, whiskers position and head position; 0-2 each). Construct validity, responsiveness, and inter- and intra-rater reliability were evaluated using linear models with Benjamini-Hochberg correction, Wilcoxon signed-rank test and single intraclass correlation coefficients (ICCsingle), respectively (P <0.05).

RESULTS

FGS total ratio scores were higher at 1 and 2 h after ovariohysterectomy (median [interquartile range, IQR]: 0.30 [0.20-0.40] and 0.30 [0.20-0.40], respectively) than at baseline (median [IQR]: 0.10 [0.00-0.30]) (P <0.001). FGS total ratio scores were lower after the administration of rescue analgesia (median [IQR] before and after rescue analgesia) 0.40 [0.20-0.50] and 0.20 [0.10-0.38], respectively (P <0.001). Inter-rater ICCsingle was 0.68 for the FGS total ratio scores and 0.35-0.70 for all AUs considered individually. Intra-rater ICCsingle was 0.77-0.91 for the FGS total ratio scores and 0.55-1.00 for all AUs considered individually.

CONCLUSIONS AND RELEVANCE

The FGS is a valid and responsive acute pain-scoring instrument with moderate inter-rater reliability and good to excellent intra-rater reliability in kittens.

Effectiveness of transdermal fluralaner in the treatment of Lynxacarus radovskyi (Acari: Listrophoridae) in naturally infested domestic cats

Mites of the species Lynxacarus radovskyi, which are commonly found on domestic cats in Brazil, can cause discomfort, itching, and alopecia. The development of new, safer and more effective treatments with a broad spectrum of activity, including the use of isoxazolines, is needed. The purpose of this study was to assess the efficacy of transdermal fluralaner in domestic cats naturally infested with L. radovskyi. Twenty cats were evaluated by trichograms and divided into two groups of 10 animals. The control group was not treated, while the treated group was given a single topical dose of fluralaner, as per the manufacturer's instructions. The cats were reassessed for the presence of L. radovskyi eggs and mites on days D+7, D+14, D+28, D+42, D+56, D+70, D+84, and D+98. As of D+42, all the animals (100%) tested negative for mites, and remained parasite-free until the end of the study, while the control group tested positive throughout the experiment. It can be concluded that a single dose of fluralaner applied topically was effective in treating cats naturally infested with L. radovskyi.

Cat Friendly Practice improves feline visits, resulting in increased laboratory testing and increased diagnosis of certain common feline conditions

OBJECTIVES

Cat Friendly Practices (CFPs) were compared with non-CFP control practices to determine whether CFPs had an increased proportion of clinical visits, number of visits per cat per year and inclusion of diagnostic testing. To measure diagnostic testing behavior, the numbers and types of tests analyzed and clinically relevant findings were compared.

METHODS

In a retrospective analysis comparing CFPs and non-CFPs, clinic financial data and associated diagnostic tests from a commercial laboratory for 2018 and 2021 were analyzed. Data were stratified based on visit type and included revenue per visit type, revenue per patient, the number of visits per year and the proportion of visits that included diagnostic testing. Analyses of clinical findings for June 2021 to June 2022 examined clinical findings associated with biochemistry, complete blood count, urinalysis and thyroid testing categories at diagnostic patient visits, the proportion of clinical visits in which each finding was observed, the volume of testing categories as a proportion of clinical visits, and the proportion of diagnostic visits with one, two, three or four testing categories.

RESULTS

The average revenue per feline visit and visits that included diagnostic testing were higher at CFPs. There was no difference in the proportion of wellness visits; however, CFPs had higher mean visits per year per patient. CFPs performed diagnostic testing at 12% more clinical visits, and had higher annual revenue per feline patient for all visits and for visits including diagnostic testing. CFPs had higher odds of patients having >1 visit that included bloodwork or urinalysis. They were more likely to include all four testing categories and less likely to include only one category at a diagnostic visit. CFPs identified a higher number of cats with clinical findings.

CONCLUSIONS AND RELEVANCE

CFPs exhibited unique diagnostic testing behavior by performing more diagnostic tests more frequently and identifying a higher number of cats with abnormal findings.

Effect of audible static on blood pressure measurement by Doppler ultrasonic sphygmomanometry in cats

OBJECTIVES

The aim of the present study was to determine whether the use of headphones to eliminate audible static during Doppler ultrasonic sphygmomanometry affects blood pressure (BP) measurement in conscious young adult (aged 1-6 years) and mature adult/senior (aged ⩾7 years) cats.

METHODS

A randomized crossover study was conducted. Healthy client-owned cats (>1 year) were enrolled. Blood pressure measurements were obtained twice, 14 days apart, with or without the use of headphones worn by a veterinarian. A fear, anxiety and stress (FAS) score (0 = relaxed; 4 = severe signs) was recorded. A linear mixed-effects model was used to compare the effect of wearing headphones on BP measurement.

RESULTS

In total, 18 young adult and 14 mature adult and senior cats with a median age of 5 years (range 1-14 years) were enrolled. Of the cats, 47% (15/32) had an average BP measurement that was at least 10 mmHg higher when using headphones compared with when not using headphones, of which a majority (11/15, 73%) were young adult cats. The average BP measurement was not different when using headphones compared with when not using headphones (mean difference -7 mmHg; 95% confidence interval -14 to 0.6; P = 0.07). When compared within age groups, the average BP measurement taken when using headphones (125 ± 15 mmHg) was lower compared with the measurement taken when not using headphones (137 ± 17 mmHg) in young adult cats (P = 0.02).

CONCLUSIONS AND RELEVANCE

The reduction in the average BP measurement with the use of headphones suggests this method may be helpful in reducing situational hypertension, particularly in young adult cats. Our findings also highlight the importance of consistent use of headphones when comparing serial measurements in a cat.

Why some canine and feline blood donors do not make the cut: A cohort study

BACKGROUND

While there has been extensive investigation into the selection and retention of human blood donors, veterinary research in this area is limited. This study aimed to identify the reasons for the rejection and withdrawal of canine and feline blood donors from a blood donation programme.

METHODS

Records of cats and dogs presenting as prospective blood donors and/or donating between 2014 and 2019 were analysed. Reasons for rejection at sign-up were categorised into medical and temperament. Reasons why animals left before retirement age were categorised into medical, temperament and owner related.

RESULTS

Data from 362 dogs and 134 cats were analysed. Cats (20.8%) were more likely to be rejected than dogs (5.2%) at sign-up, mostly due to medical reasons. Both species often left the blood donor service early due to temperament reasons. Owner and medical reasons for leaving early were also common.

LIMITATION

This was a retrospective study with subjective assessment of temperament.

CONCLUSIONS

Inability to donate due to temperament and medical reasons is common. When recruiting blood donors, it should be recognised that a fairly high proportion will not be successful. Owner understanding and motivation are essential to ensure successful selection and retention of donors, which allows amortisation of recruitment costs.

Pain in Pets: Beyond Physiology

Animals do not speak a language humans understand, making it easy to believe that they do not experience pain the way humans do. Despite data affirming that companion animals can and do experience pain much as do humans, there remains a gap between companion animal acute pain management knowledge and its execution. Companion animal pain is not simply a physiological issue. Veterinary clinicians can and should embrace the foundational principles of clinical bioethics-respect for autonomy, nonmaleficence, beneficence, and justice-translated from human medicine for the benefit of their patients. By reframing companion animal pain as a bioethical issue, as described in this paper, veterinarians affirm their commitment to closing the gap between what is known and what is done for painful companion animals. This takes pet pain beyond physiology.

Feline Stress Management During air Travel: A Multimodal Approach

PRACTICAL RELEVANCE

More cats are travelling by air every year; however, air travel involves several common causes of stress for cats, such as environmental changes and a lack of control and predictability. The use of a multimodal stress management protocol for all stages of the relocation process, including appropriate and effective anxiolytic medication where necessary, is therefore important in order to safeguard the cat's welfare while travelling.

CLINICAL CHALLENGES

Cats may be presented to veterinarians for the purpose of preparing them and/or their documentation for air travel. Maintaining and protecting a cat's physical, mental and emotional health in a stressful environment, while subjected to likely unfamiliar sights, noises, smells and the movement of the aircraft, and additionally dealing with international legislation, regulations and documents, can pose a complex challenge to veterinarians.

AIMS

This review describes the importance of stress management during air travel for cats, aims to raise awareness about the often poorly understood challenges involved, and outlines effective and airline-compliant stress management modalities. While the discussion is focused on air travel specifically, the stress management methods described can be applied to all types of longer distance travel, such as a long road trip or a ferry crossing, as well as a stay in a holiday home.

EVIDENCE BASE

There are currently no studies specifically on air travel in cats and, similarly, there are also limited data on air travel in other species. Many of the recommendations made in this review are therefore based on the authors' extensive experience of preparing pets for travel, supported by published data when available.

Integrating Communication Skills, Awareness of Self and Others, and Reflective Feedback into One Inclusive Anatomical Representation of Relationship-Centered Health Care

The American Veterinary Medical Association Council on Education mandates in standard 11 that all accredited colleges of veterinary medicine must develop and deliver formal processes by which students are observed and assessed in nine competencies. The eighth competency combines clinical communication and sensitivity toward soliciting and understanding individual narratives across a diverse clientele to facilitate health care delivery. Several frameworks have been designed to structure health care consultations for teaching and coaching purposes. The Calgary-Cambridge guide (CCG) provides an evidence-based approach to outlining the flow of consultations, incorporating foundational communication skills and elements of relationship-centered care into a series of sequential tasks. Although the CCG was intended for use as a flexible tool kit, it lacks visible connections between concrete experiences (e.g., the consultation) and reflective observation (e.g., the feedback). This teaching tip describes the development of a novel anatomical representation of the consultation that integrates process elements of the CCG with other core curricular concepts. By combining knowledge, technical skills, critical thinking, reflection, cultural humility, and self-awareness into a skeletal consultation model, linkages are established between communication and intergroup dialogue skills, diversity and inclusion (D&I). This model has been further adapted as feline, caprine, porcine, equine, avian, and reptilian versions for in-class use as strategic visual aids that highlight key areas of focus for Professional Skills class sessions. Future developments by the authors will explore how to link species-specific consultation models to assessment rubrics to reinforce the connection between content (what) and process (how).

Evaluation of the effects of gabapentin on the physiologic and echocardiographic variables of healthy cats: a prospective, randomized and blinded study

OBJECTIVES

The aim of this study was to evaluate, using echocardiography, the effects of oral administration of a single dose of gabapentin on the physiologic variables (heart rate [HR], respiratory rate [RR] and systolic blood pressure [SBP]) and systolic and diastolic cardiac function of healthy cats.

METHODS

This was a prospective, randomized and blinded study with 40 healthy cats aged between 6 months and 2 years. The cats' health status was assessed on the first appointment (T1) when they underwent a physical examination, complete blood count, biochemical profile, assessment of physiologic variables and echocardiogram. The echocardiogram was used to measure the left ventricle's (LV) internal diameter during systole and diastole, isovolumic relaxation time, transmitral flow, E-wave deceleration time and HR. The cats were randomly divided into two groups: (1) a treatment group with 20 cats that received a single oral dose of gabapentin (100 mg/cat); and (2) a control group with 20 cats that received a single oral dose of placebo. All variables of the physiologic and echocardiographic variables were re-evaluated 1-3 weeks after T1 (T2), 90 mins after medication or placebo administration.

RESULTS

There was no difference in the physiologic variables evaluated in both groups. The proportion of cats in the treatment group that had their ventricular filling waves fused on T1 but did not have them fused on T2 was significantly higher (45%) compared with cats in the control group (15%; P = 0.0384).

CONCLUSIONS AND RELEVANCE

There was no difference between the groups in regard to SBP, HR, RR and echocardiographic variables. Gabapentin improved evaluation of diastolic function on echocardiogram because it reduced the fusion of ventricular filling waves during the evaluation of the diastolic function of the LV. Gabapentin did not cause adverse effects on the cardiovascular hemodynamics of young healthy cats.

2022 AAFP/ISFM Cat Friendly Veterinary Interaction Guidelines: Approach and Handling Techniques

PRACTICAL RELEVANCE

The '2022 AAFP/ISFM Cat Friendly Veterinary Interaction Guidelines: Approach and Handling Techniques' (hereafter the 'Cat Friendly Veterinary Interaction Guidelines') support veterinary professionals with feline interactions and handling to reduce the impact of fear and other protective (negative) emotions, in so doing enhancing feline welfare and In implementing these Guidelines, team satisfaction and cat caregiver confidence in the veterinary team will increase as the result of efficient examinations, better experience, more reliable diagnostic testing and improved feline wellbeing. Veterinary professionals will learn the importance of understanding and appropriately responding to the current emotional state of the cat and tailoring each visit to the individual.

CLINICAL CHALLENGES

Cats have evolved with emotions and behaviors that are necessary for their survival as both a predator and prey species. A clinical setting and the required examinations and procedures to meet their physical health needs can result in behavioral responses to protective emotions. Cat friendly interactions require understanding, interpreting and appropriately responding to cats' emotional states and giving them a perceived sense of control while performing the required assessment.

EVIDENCE BASE

These Guidelines have been created by a Task Force of experts convened by the American Association of Feline Practitioners and the International Society of Feline Medicine, based on an extensive literature review and, where evidence is lacking, the authors' experience.

ENDORSEMENTS

These Guidelines have been endorsed by a number of groups and organizations, as detailed on page 1127 and at catvets.com/interactions and icatcare.org/cat-friendly-guidelines.

Outreach Medicine as an Experiential Teaching Tool to Improve Veterinary Student and Client Education

Outreach medicine is used to improve students' medical, technical, behavioral, and communication training among health professional schools; it is also used in veterinary schools, but little has been described on its educational impacts among pre-clinical veterinary students. Aiming to train practice-ready graduates, we established a monthly nonprofit vaccine clinic serving low-income clients to provide pre-clinical veterinary students with a realistic experiential learning environment. We developed surveys to assess the educational impacts of outreach medicine on pre-clinical veterinary student and client education. We received 101 student surveys, 26 educator (i.e., veterinarians and registered veterinary technicians) surveys, and 96 client surveys. Veterinarians, students, and technicians reported that students improved in important veterinary skills such as client communication, subcutaneous injection, patient handling, and physical examination. They also reported improved confidence in students' clinical decision making. Veterinarians valued the vaccine clinic as a favorable educational tool to teach behavior assessment and low-stress handling, and they highlighted that experiential learning via the vaccine clinic provided students with a clinical experience representative of most veterinarian practices (i.e., small animal general practitioner). Clients reported that the clinic's students and veterinarians greatly improved their knowledge of their pets' care and vaccines-notably, their knowledge of rabies and leptospirosis improved. Outreach medicine in the form of a vaccine clinic creates valuable experiential learning opportunities that increase veterinary student preparedness and complement didactic, laboratory, and case-based teaching.

Effect of mineral oil as a lubricant to collect feces from cats for microbiome studies

BACKGROUND

Fecal specimens are critical for disease screening, diagnosis, and gut microbiome research. For domestic cats, lubricants are often necessary to obtain a sufficient quantity of sample. However, the effect of lubrication on feline microbiome analysis has not been assessed.

OBJECTIVES

To evaluate if lubrication using mineral oil during cat feces sample collection affects the DNA extraction, metagenomic sequencing yield, and the microbial composition and diversity in subsequent gut microbiome analyses.

ANIMALS

Eight 6-year-old male, neutered, domestic short-haired cats housed in a research facility.

METHODS

Cohort study. The gut microbiomes were investigated for fecal sample collection with and without lubrication using whole-genome shotgun metagenomic sequencing.

RESULTS

Fecal specimens were collected using a fecal loop under sedation without lubrication and with mineral oil lubrication. There were no significant differences between the 2 groups in the microbial DNA yield in ng/mg fecal sample (75.75 [25.8-125.7] vs 60.72 [33.49-87.95], P = .95), metagenomic sequencing yield in Gbp (10.31 [6.29-14.32] vs 13.53 [12.04-15.02], P = .2), proportion of host contamination (0.1 [0.02-0.18] vs 0.15 [0-0.3], P = .84), relative taxonomy abundance (P > .8), or the number of microbial genes covered (408 132 [341 556-474 708] vs 425 697 [358 505-492 889], P = .31).

CONCLUSIONS AND CLINICAL IMPORTANCE

Fecal sampling with mineral oil lubrication did not change the microbial DNA extraction yield, metagenomic sequencing yield, level of host contamination, the microbial composition and diversity in subsequent gut microbiome analyses. Here we reported a proven cat-friendly protocol for fecal sample collection in clinical and research setting for gut microbiome analyses.

Perception of stress in cats by German cat owners and influencing factors regarding veterinary care

OBJECTIVES

Visiting the veterinarian is generally perceived as a stressful situation for cats. Previous studies have shown that the perception of stress may influence cats' healthcare. In order to minimise stress in cats during the veterinary consultation, feline-friendly handling has gained importance and is increasingly being used. The aim of this study was to find out whether cats experience stress during a visit to the veterinarian (and, if so, to what extent), and which factors influence the perception of stress and whether feline-friendly handling techniques have an impact.

METHODS

An online survey was conducted among German cat owners. In total, 889 questionnaires were evaluated. The results were analysed with binary logistic regression and a χ² test. A principal component analysis was used to detect the main influencing factors on the perception of stress.

RESULTS

Most of the cats (88.7%, n = 732/825) were perceived as stressed during a veterinary consultation, while only about half of the owners (50.8%, n = 419/824) stated that they felt stressed themselves. The cat owners (n = 819) who perceived visiting the veterinarian as a stressful situation also described their cat as stressed significantly more often compared with owners who did not feel stressed (χ² = 101.113, P <0.001). The probability that owners experienced stress themselves was significantly increased if they perceived their cat to be stressed too (odds ratio 0.073, 95% confidence interval 0.016-0.328). One factor that influenced whether an owner was stressed was the stress behaviour of their cat (P <0.001). Furthermore a feline-friendly demeanour by the veterinarian led to less stress in the owners (P <0.001).

CONCLUSIONS AND RELEVANCE

The owner's stress influences the perception of their cat's stress. By adhering to feline-friendly handling guidelines, veterinarians can reduce owner stress associated with veterinary visits, thereby promoting optimal veterinary care and health for their feline patients.

Effect of a synthetic feline facial pheromone product on stress during transport in domestic cats: a randomised controlled pilot study

OBJECTIVES

Transport can be a stressful experience for domestic cats. The objective of this study was to evaluate the effect of a new synthetic feline facial pheromone product on relieving stress in domestic cats during short-distance transport.

METHODS

A randomised, blinded, placebo-controlled pilot study was conducted. Prior to baseline screening, cat owners were trained via online meetings in the assessment of stress-related behaviours and overall stress visual analogue scoring. All assessments were completed 30 mins after the start of transport. A total of 150 domestic cats exhibiting stress-related behaviours during baseline screening were recruited and randomly assigned to either the treatment group (n = 75) or the placebo group (n = 75). For the placebo-controlled intervention, the product and placebo, which were identical in appearance, were provided to the treatment and placebo groups, respectively. Fifteen minutes after spraying the carriers with the product or placebo, cat owners were required to take their cat out and complete the same assessments (baseline screening).

RESULTS

After the intervention, the performance of the stress-related behaviours curling, lack of motion and meowing during transport outside the home was significantly reduced in the treatment group compared with the placebo group (P <0.05). When the baseline stress visual analogue scale (VAS) score was >2.94 cm, cats in the treatment group had significantly lower post-intervention stress VAS scores compared with those in the placebo group (P <0.05).

CONCLUSIONS AND RELEVANCE

A synthetic feline facial pheromone product can alleviate short-distance transport-related stress in domestic cats with higher stress scores. This finding will benefit domestic cats during transport outside of the home.

Hematological Parameters from the Feline Blood Donor to the Blood Unit: What Changes Are to Be Expected?

Simple Summary

Feline blood donation requires sedation to allow for good blood collection, avoiding venous damage and unnecessary donor stress. In the present study, we describe the variation of hematological parameters in a population of healthy blood-donor cats that underwent the same sedation protocol, including medetomidine, alfaxalone, and butorphanol. Significant differences in hematological parameters were observed between unsedated and sedated cats; particularly, the mean red blood cell count, hemoglobin concentration, hematocrit value, mean corpuscular volume, and red blood cells distribution width were significantly lower in sedated cats than in conscious ones, thus confirming that sedation is a critical procedure in cats. No significant differences for the main hematological parameters were observed between sedated cats and feline blood units, suggesting that the dilution with the conservative–anticoagulant solution (ratio 1:7) exerts negligible effects on these parameters with respect to samples of sedated animals.

Abstract

Feline blood donation requires sedation to allow for good blood collection, avoiding venous damage and unnecessary donor stress. In the present study, we describe the variation of hematological parameters in a population of 74 healthy blood-donor cats that underwent the same sedation protocol, including medetomidine, alfaxalone, and butorphanol. Changes in hematological parameters were evaluated in blood samples collected from conscious cats (group A), sedated cats (group B), and feline whole-blood units (FBUs) (group C). Significant differences were observed between unsedated and sedated cats: the mean RBC count, HGB, HCT, and RDW were significantly lower in sedated cats than in conscious ones, with a difference of 17.95%, 18.42%, 28.21%, and 10.00%, respectively. In accordance with previously reported data, our results confirm that sedation is a critical procedure in cats that can affect most of the hematological parameters. The second finding of our study is that no significant differences for the main hematological parameters were observed between sedated cats and FBUs, thus suggesting that the dilution with the conservative–anticoagulant solution exert negligible effects on these parameters with respect to samples of sedated animals. This hematological change must be taken into consideration since such parameters are important to define the quality of FBUs.

2022 ISFM Consensus Guidelines on Management of the Inappetent Hospitalised Cat

PRACTICAL RELEVANCE

Inappetence may have many origins and, as a presenting sign or observation in the hospitalised patient, is common in feline practice. Nutritional assessment of every patient is encouraged, to identify the need for, and appropriate type of, intervention indicated. The impact of malnutrition may be significant on the feline patient, perpetuating illness, delaying recovery, slowing wound healing and negatively impacting gut health and immunity. Delayed intervention may result in the cat's deterioration; hence prompt control of contributing factors such as the underlying illness, pain, nausea, ileus and stress is vital to optimise voluntary food intake. Management is multimodal, comprising reduction of stress, medications and assisted nutrition in the form of tube feeding or parenteral nutrition. Use of antiemetic, analgesic, prokinetic and appetite stimulant medications may restore appetite, but placement of feeding tubes should not be delayed. Feeding tubes are generally well tolerated and allow provision of food, water and medication with minimal stress, although clinicians must be aware of complications such as stoma site infections and refeeding syndrome.

CLINICAL CHALLENGES

Cats are vulnerable to malnutrition owing to their unique metabolism and specific nutritional requirements. Moreover, their nature as a species means they are susceptible to stress in the hospital environment, which may result in reduced food intake; previous negative experiences may compound the problem. In particular, an inappropriate clinic environment and/or handling may cause or exacerbate inappetence in hospitalised patients, with negative impacts on recovery. Postponing interventions such as feeding tube placement to await improvement, owing to clinician or caregiver apprehension, may hinder recovery and worsen nutritional deficits.

EVIDENCE BASE

The 2022 ISFM Consensus Guidelines on Management of the Inappetent Hospitalised Cat have been created by a panel of experts brought together by the International Society of Feline Medicine (ISFM). Information is based on the available literature, expert opinion and the panel members' experience.

Feline blood donation adverse reactions: classification and description of acute and delayed reactions in a donor population

OBJECTIVES

This article aims to analyse the safety of feline blood donation by describing the frequency and nature of any adverse reactions and their causes, as well as propose measures to decrease the incidence of adverse reactions.

METHODS

In this prospective study, any blood donor adverse reactions detected by the clinical staff during and immediately after donation were recorded. The owners of the cats were also surveyed by a veterinary practitioner or veterinary nurse 5 days after donation, using a predefined questionnaire to assess for any clinical or behavioural changes. Data were collected between January 2019 and March 2020 from blood donors enrolled in an animal blood bank programme.

RESULTS

Of 3690 blood donations from 1792 feline donors assessed, post-donation reactions were reported in 1.14% (n = 42): 0.22% (n = 8) were acute reactions, which included weakness, pallor, tachypnoea and open-mouth breathing; and 0.92% (n = 34) were delayed post-donation reactions, with 0.16% involving cutaneous (haematomas and skin rashes, n = 6), 0.68% involving behavioural (n = 25) and 0.08% involving digestive (emesis and inappetence, n = 3) signs.

CONCLUSIONS AND RELEVANCE

The low incidence of post-donation reactions in this study is encouraging, suggesting that a well-established protocol and competent staff can help to ensure a high level of safety in a feline donor programme and, in turn, increase the confidence of cat owners.

Is methylprednisolone acetate-related insulin resistance preventable in cats?

Methylprednisolone acetate (MPA) is often prescribed to cats despite being recognized eventually as diabetogenic. To assess MPA-related insulin resistance and evaluate the efficacy of metformin or an obesity and diabetes mellitus (O&D) adjuvant diet as protective factors, a randomized clinical trial was conducted with 28 owned cats undergoing glucocorticoid therapy. A single MPA dose of 20 mg intramuscularly was administered to each cat. Controls (n=10) received only MPA. In the diet group (n=9), replacement of their habitual diet by ad-libitum feeding of a feline commercial O&D diet (Equilíbrio O&D, Total Alimentos ADM) was made. In the metformin group (n=9), metformin chlorhydrate 25mg/cat PO/q24h was administered for 30 days. All patients were clinically evaluated at baseline (T0), day 15 (T15), and day 30 (T30) and blood draw for complete blood count, serum biochemistry, and determination of insulin concentrations. Fasting Insulin Sensitivity Index (SI), Amended Insulin to Glucose Ratio (AIGR), Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), and Homeostatic Model Assessment of beta-cell function (HOMA-B) were calculated based on fasting glycemia and insulinemia. All groups showed significantly higher levels (p < 0.05) of neutrophils, albumin, glucose, cholesterol, triglycerides, and serum insulin at T15. Patients in the metformin group showed also higher SI, AIGR, and HOMA-IR results at T15. Also, at T15, reduced levels (p < 0.05) of eosinophils, lymphocytes, and creatinine were documented in all groups. An MPA single dose induced changes in insulin sensitivity in cats; however, neither metformin nor O&D feeding used in this study was effective as protective factors against MPA-related insulin resistance.

Evaluation of the Attitudes and Confidence of Veterinary Undergraduates toward Working with Cats in the Veterinary Hospital Environment

An understanding of feline behavior is required to successfully handle cats in the hospital environment and avoid triggering escalation to fear-aggression due to heightened anxiety. Some veterinary students appear to misinterpret feline behavioral cues, resulting in frustration and poor success when performing basic handling. This article investigates the following in regard to veterinary students and feline handling: (a) attitudes toward working with feline patients in the hospital environment; (b) experience of working with feline patients; (c) satisfaction in acquisition of feline handling and examination skills; and, (d) confidence in feline handling skills; and to explore influencing factors. An electronic questionnaire was circulated to fourth and final year veterinary students (May 2012) and final year students (June 2013) for anonymous voluntary completion. One hundred and seventy-three of 293 students completed the questionnaire. Of final year respondents, 87/115 (75.7%) indicated that they enjoy interacting with cats in veterinary hospitals; 95/115 (82.6%) indicated that they were satisfied with their cat handling skills; 105/115 (91.3%) felt confident handling quiet and wriggly cats; significantly fewer 63/115 (54.8%) felt confident handling unpredictable cats (p < .05). Factors significantly affecting confidence in handling unpredictable cats included: frequency of examination practice during extra-mural studies (p < .05), enjoyment of interacting with cats in veterinary hospitals (p < .05), self-perceived understanding of feline behavior (p < .05), self-perceived ability to interpret cats' behavioral expressions (p < .05), satisfaction with cat handling skills (p < .05), and perception of feline versus canine handling ability (p < .05).

2022 ISFM Consensus Guidelines on the Management of Acute Pain in Cats

PRACTICAL RELEVANCE

Increases in cat ownership worldwide mean more cats are requiring veterinary care. Illness, trauma and surgery can result in acute pain, and effective management of pain is required for optimal feline welfare (ie, physical health and mental wellbeing). Validated pain assessment tools are available and pain management plans for the individual patient should incorporate pharmacological and non-pharmacological therapy. Preventive and multimodal analgesia, including local anaesthesia, are important principles of pain management, and the choice of analgesic drugs should take into account the type, severity and duration of pain, presence of comorbidities and avoidance of adverse effects. Nursing care, environmental modifications and cat friendly handling are likewise pivotal to the pain management plan, as is a team approach, involving the cat carer.

CLINICAL CHALLENGES

Pain has traditionally been under-recognised in cats. Pain assessment tools are not widely implemented, and signs of pain in this species may be subtle. The unique challenges of feline metabolism and comorbidities may lead to undertreatment of pain and the development of peripheral and central sensitisation. Lack of availability or experience with various analgesic drugs may compromise effective pain management.

EVIDENCE BASE

These Guidelines have been created by a panel of experts and the International Society of Feline Medicine (ISFM) based on the available literature and the authors' experience. They are aimed at general practitioners to assist in the assessment, prevention and management of acute pain in feline patients, and to provide a practical guide to selection and dosing of effective analgesic agents.

Clinical evaluation of the effects of a single oral dose of gabapentin on fear-based aggressive behaviors in cats during veterinary examinations

OBJECTIVE

To investigate the effects of a single oral dose of gabapentin on fear-based aggressive behaviors (FABs) in cats during veterinary examinations.

ANIMALS

55 healthy pet cats (26 with and 29 without a history of FAB during veterinary visits [FAB and untreated control groups, respectively]).

PROCEDURES

A standardized 9-step clinical examination protocol (with patient compliance scored from 0 to 9 according to the highest completed step) was tested on untreated control group cats. The protocol was then used in a double-blind, randomized, placebo-controlled, crossover-design trial in which FAB-group cats received owner-administered gabapentin (100 or 200 mg/cat) or placebo capsules 2 hours before the first of 2 veterinary visits and received the alternate treatment before the second visit ≥ 1 day later. Ease of administration (scored from 1 [very difficult] to 4 [very easy]) and adverse effects were recorded. Compliance scores were compared between treatments for the FAB group and between FAB and untreated control groups. Changes in scores between treatments for the FAB group were used to investigate associations between selected variables and the outcome of interest.

RESULTS

FAB group compliance scores after gabapentin administration (median, 9; range, 0 to 9) were significantly higher than scores after placebo administration (median 0.5; range, 0 to 7) and did not differ from scores for the untreated control group. Owner scores indicated capsule administration was easy. Adverse effects (most commonly drowsiness, myorelaxation, and ataxia) resolved ≤ 10 hours after detection.

CONCLUSIONS AND CLINICAL RELEVANCE

Results suggested oral administration of gabapentin to cats 2 hours before a veterinary visit can reduce FAB during physical examination, enabling more complete evaluation.

Comparative Assessment of Heart Rate Variability Obtained via Ambulatory ECG and Polar Heart Rate Monitors in Healthy Cats: A Pilot Study

Chronic exposure to stressful environments can negatively impact cats' health and welfare, affecting behavioral, autonomic, endocrine, and immune function, as with cats in shelters. Low-stress handling practices likely improve shelter cat welfare, but data supporting improved outcomes remain limited. Cardiac activity, particularly heart rate variability (HRV), is an indicator of stress and emotional state in humans and non-human animals, tracking important body functions associated with stress responsiveness, environmental adaptability, mental, and physical health. HRV studies in cats are limited, involving mainly anesthetized or restrained cats. This pilot study tested the feasibility of obtaining HRV data from unrestrained cats, using a commercially available cardiac monitoring system (Polar H10 with chest strap), compared with data from a traditional ambulatory electrocardiogram. Simultaneous data for the two systems were obtained for five adult cats. Overall, the Polar H10 monitor assessments of HRV were lower than the true HRV assessment by ambulatory ECG, except for SDNN. Correlation between the two systems was weak. Possible reasons for the lack of agreement between the two methods are discussed. At this time, our results do not support the use of Polar H10 heart rate monitors for studies of HRV in cats.

Prevalence, association with systemic inflammatory response syndrome and outcome of stress hyperglycaemia in sick cats

OBJECTIVES

To determine the prevalence of stress hyperglycaemia in sick cats, and to investigate the association of stress hyperglycaemia with systemic inflammatory response syndrome and outcome.

MATERIALS AND METHODS

Medical records (2004 to 2013) from sick cats admitted to the Medicine Unit of a Veterinary Teaching Hospital were retrospectively reviewed. Cases were enrolled if a serum glucose measurement and a complete medical record were available. Cats that were healthy, hypoglycaemic, diabetic, sedated or had a previous administration of drugs (apart from vaccination and deworming) were excluded.

RESULTS

The study included 647 cats; stress hyperglycaemia (serum glucose >8.3 mmol/L) was found in 194 (30%) cats, while 453 (70%) cats were normoglycaemic. The prevalence of systemic inflammatory response syndrome was significantly higher in cats with stress hyperglycaemia (25/174, 14.4%) compared to normoglycaemic cats (26/399, 6.5%). Significantly, more cats with stress hyperglycaemia were hospitalised [97/194 (50.0%)] compared to normoglycaemic cats [171/453 (37.7%)]. However, the median duration of hospitalisation was not significantly different [4 (1 to 26) days and 4 (1 to 24) days, respectively]. The prevalence of cats with negative outcome was not significantly different between the two groups (cats with stress hyperglycaemia: 37.1%, normoglycaemic cats: 33.9%). Nonetheless, when modelling of outcome prediction included breed, age, stress hyperglycaemia and disease category as factors, cats with stress hyperglycaemia had 2.8 times the odds to have a negative outcome (95% confidence interval: 1.3 to 6.4).

CLINICAL SIGNIFICANCE

Based on the cut-off employed in this study, Stress hyperglycaemia, as defined by the cut-off is common in sick cats. Stress hyperglycaemia is associated with systemic inflammatory response syndrome development and seem to be a negative prognostic indicator.

Evaluation of hair and nail cortisol concentrations and associations with behavioral, physical, and environmental indicators of chronic stress in cats

Background

Chronic stress is implicated in behavioral and health issues in cats, but methods for recognition, evaluation, and measurement of stress are lacking. Cortisol concentration is typically used as an indicator of stress.

Objectives

To evaluate use of an enzyme immunoassay to quantitate hair and nail cortisol concentrations (HCC and NCC) in cats and evaluate associations between HCC and NCC and behavioral, physical, and environmental correlates of chronic stress in cats.

Animals

Forty‐eight adult, owned or community cats.

Methods

Cross‐sectional study. Nail clippings and hair were collected from cats. Medical history and cat daily lifestyle questionnaires were completed by owners or caretakers. A commercial laboratory performed cortisol extraction and quantification using a validated enzyme immunoassay kit. Correlational and regression analyses were used to evaluate associations between HCC and NCC and behavioral, environmental, and medical factors.

Results

Hair and nail cortisol concentrations were significantly associated (r_s = 0.70; P < .001), but HCCs varied widely within and among cats. Cats with litterbox issues had significantly increased HCC (P = .02) and NCC (P = .001) as compared to cats without litterbox issues. Cats with groomed coats had lower HCCs (P = .02) as compared to cats without groomed coats, whereas cats with dander and mats had higher NCCs (P = .01) as compared to cats without dander and mats.

Conclusions and Clinical Importance

The quantification of NCCs might improve identification and evaluation of chronic stress in cats. The variability of HCCs in individual cats warrants caution using this measurement in chronic stress studies.

Providing Humans With Practical, Best Practice Handling Guidelines During Human-Cat Interactions Increases Cats' Affiliative Behaviour and Reduces Aggression and Signs of Conflict

The importance of animals' experiences and associated comfort during Human-Animal Interactions (HAI), and particularly Animal Assisted Interventions (AAI), are increasingly recognised. However, there remains a paucity of published research, particularly concerning less formal but frequent HAIs to which companion animals are typically exposed, such as stroking or petting. Additionally, few practical evidence-based guides to facilitate humans' optimal animal handling and interaction in these contexts exist. A simple set of Human-Cat Interaction (HCI) guidelines were therefore created, with the aim to enhance domestic cats' comfort during generic HCI contexts. Based around a “CAT” acronym, guidelines focused on providing the cat with choice and control (“C”), paying attention (“A”) to the cats' behaviour and body language and limiting touch (“T”), primarily to their temporal regions. Guidelines were presented to human participants during a brief training intervention, and guideline efficacy was subsequently assessed. Domestic cats available for rehoming at Battersea Dogs and Cats Home, UK (n = 100) were filmed during interactions with novel members of the public (n = 120). Cats were exposed to a maximum of six, 5-min interaction sessions, balanced across “control” (interactions with humans pre-training) and “intervention” conditions (interactions with humans post-training). For each observation, cat behaviour and posture were coded and humans' cat-directed behaviour rated on the degree to which it reflected best practice principles. Data were extracted from a total of 535 observations and average human interaction ratings and cat behaviour values compared between control and intervention conditions via paired Wilcoxon tests. Compared to the control, humans' interaction styles were rated as significantly more closely aligned with best practice principles in the intervention condition. Cats also displayed significantly greater frequencies and/or durations of affiliative and positively-valenced behaviours in the intervention. In contrast, cats in the control displayed significantly greater frequencies of human-directed aggression, in addition to greater frequencies and/or durations of behaviours associated with conflict and negative valence. Results demonstrate the positive impact of practical interaction guidelines on cats' social behaviour and comfort during HCI, with the potential to improve cats' general experiences during interactions, reduce human-directed aggression and ultimately improve cat-human relationships.

Effects of Pre-Anesthesia Anxiety on Propofol Induction Dose in Cats

Simple Summary

In humans, the anxiety felt by patients before anesthesia reportedly increases the anesthetic requirements for anesthesia induction. Relieving the patient’s anxiety before anesthesia is necessary to prevent the excessive administration of anesthetic. However, no studies have been conducted on the effects of anxiety on anesthesia induction in cats. Therefore, we aimed to investigate the impact of the anxiety healthy cats felt before anesthesia on the propofol dose required for inducing anesthesia. We observed that significant behavioral changes due to anxiety did not increase the propofol dose requirements in the cats compared to those who experienced no anxiety. Furthermore, there was no difference in the maintenance and recovery from anesthesia between the two aforementioned conditions. In conclusion, anxiety due to changing circumstances did not change the propofol dose required for anesthesia induction in cats, despite significant changes in their behavior.

Abstract

In humans, peri-anesthesia anxiety reportedly increases the anesthetic requirements for anesthesia induction. However, no studies have been conducted on cats regarding the effects of anxiety on anesthesia induction or anesthetic-mediated physiological changes. Therefore, we intended to investigate the effect of pre-anesthesia anxiety in healthy cats on the propofol dose required for anesthesia induction, and its impact on behavioral and physiological evaluations. The cats were placed in either a calm (CAL) or tense (ANX) environment. We performed physiological and behavioral evaluations before and after each environmental acclimatization period. Anesthesia was induced using propofol. We recorded the total dose of propofol administered for each clinical sign observed during anesthesia induction. The post-acclimatization behavioral evaluation score was significantly higher in the ANX group than the pre-acclimatization score. However, there was no significant difference in the propofol dose required for each clinical sign in the ANX or CAL groups. There were also no significant differences in the physiological evaluations between the ANX and CAL groups. Therefore, pre-anesthesia anxiety felt by cats did not affect propofol-mediated anesthesia induction.

2021 AAFP Feline Senior Care Guidelines

The '2021 AAFP Feline Senior Care Guidelines' are authored by a Task Force of experts in feline clinical medicine and serve as an update and extension of those published in 2009. They emphasize the individual patient evaluation and the process of aging, with references to other feline practice guidelines for a more complete discussion of specific diseases. Focusing on each cat encourages and empowers the owner to become a part of the cat's care every step of the way. A comprehensive discussion during the physical examination and history taking allows for tailoring the approach to both the cat and the family involved in the care. Videos and analysis of serial historical measurements are brought into the assessment of each patient. These Guidelines introduce the emerging concept of frailty, with a description and methods of its incorporation into the senior cat assessment. Minimum database diagnostics are discussed, along with recommendations for additional investigative considerations. For example, blood pressure assessment is included as a minimum diagnostic procedure in both apparently healthy and ill cats. Cats age at a much faster rate than humans, so practical timelines for testing frequency are included and suggest an increased frequency of diagnostics with advancing age. The importance of nutrition, as well as senior cat nutritional needs and deficiencies, is considered. Pain is highlighted as its own syndrome, with an emphasis on consideration in every senior cat. The Task Force discusses anesthesia, along with strategies to allow aging cats to be safely anesthetized well into their senior years. The medical concept of quality of life is addressed with the latest information available in veterinary medicine. This includes end of life considerations like palliative and hospice care, as well as recommendations on the establishment of 'budgets of care', which greatly influence what can be done for the individual cat. Acknowledgement is given that each cat owner will be different in this regard; and establishing what is reasonable and practical for the individual owner is important. A discussion on euthanasia offers some recommendations to help the owner make a decision that reflects the best interests of the individual cat.

Human sporotrichosis outbreak caused by Sporothrix brasiliensis in a veterinary hospital in Southern Brazil

Sporotrichosis is a mycotic disease caused by Sporothrix spp., whose zoonotic transmission by sick cats is the main infection route in Brazil. The aim of the current study is to report a human sporotrichosis outbreak caused by zoonotic transmission from a feline, with emphasis on the importance of making differential diagnosis and of using personal protective equipment. A hospital team member presented injury in the arm after having handled a cat that had been hospitalized for being hit by a car. The animal presented skin lacerations, myiasis, and full tibial fracture - there were no other signs of skin lesions. Clinical samples were collected from both the human and the suspected cat, for mycological culture; results have shown Sporothrix sp. growth. A search was conducted to identify other hospital team members who also had contact with the animal. Other six individuals also had suspected lesions in their arms, hands and ocular area; they were all subjected to sample collection. Mycological results have also confirmed Sporothrix spp.; sequencing analysis has shown that all seven humans were infected with Sporothrix brasiliensis. Since Southern Brazil is endemic of this disease, it is worth emphasizing the importance of taking into consideration zoonotic risks at the time to provide emergency care to stray animals, mainly felines, as well as of using Personal Protective Equipment while handling them - regardless of whether they present, or not, typical clinical symptoms or history of the disease, given the potential zoonotic risk posed by Sporothrix brasiliensis.

Sedative effects of acepromazine in combination with nalbuphine or butorphanol, intramuscularly or intravenously, in healthy cats: a randomized, blinded clinical trial

OBJECTIVES

The aim of this study was to compare the sedative effects in cats administered acepromazine-nalbuphine and acepromazine-butorphanol, intramuscularly (IM) and intravenously (IV), and the occurrence of adverse cardiorespiratory effects.

METHODS

Forty-six cats were randomly divided into four groups and administered acepromazine (0.05 mg/kg) combined with nalbuphine (0.5 mg/kg) or butorphanol (0.4 mg/kg), IV (ACP-NALIV and ACP-BUTIV groups, respectively) or IM (ACP-NALIM and ACP-BUTIM groups, respectively). Sedation scores, ease of intravenous catheter placement (simple descriptive scale [SDS] scores), physiologic variables, venous blood gases and the propofol dose required for anesthetic induction were recorded.

RESULTS

Mild sedation was observed in all groups approximately 30 mins after treatment administration (timepoint T1, prior to propofol administration). Sedation scores at T1 increased above baseline in all groups (P <0.05), but no significant difference was observed among groups. Dynamic interactive visual analogue scale sedation scores (range 0-100 mm) recorded at T1 were (median [interquartile range]): ACP-NALIM, 12 (10-12); ACP-NALIV, 11 (6-16); ACP-BUTIM, 11 (7-14); and ACP-BUTIV, 12 (7-19). Overall, SDS scores did not change from baseline at T1 and there was no significant difference among groups. The propofol dose did not differ among groups. Blood gases remained within the reference intervals for cats. Significant decreases from baseline were detected for all groups in systolic arterial pressure (SAP). Mean ± SD values at T1 were (mmHg): ACP-NALIM, 108 ± 13; ACP-NALIV, 102 ± 10; ACP-BUTIM, 97 ± 13; and ACP-BUTIV, 98 ± 21. Arterial hypotension (SAP <90 mmHg) was recorded at T1 in 0/11, 1/13, 4/11 and 5/11 cats in groups ACP-NALIM, ACP-NALIV, ACP-BUTIM and ACP-BUTIV, respectively, and was further exacerbated after the induction of anesthesia with propofol.

CONCLUSIONS AND RELEVANCE

In healthy cats administered acepromazine-nalbuphine and acepromazine-butorphanol, IM and IV, the degree of sedation was mild regardless of the protocol and the route of administration. The main adverse effect observed was a reduction in arterial blood pressure.

Design and Validation of a Simulator for Feline Cephalic Vein Cannulation-A Pilot Study

In recent years there has been an increased use of alternative methods for teaching veterinary clinical skills, since ethical considerations preclude the use of live animals for demonstration or practice of many procedures. Skills training on cats (i.e., feline venipuncture) is a particularly challenging area. This study aimed to develop a simulator for cephalic venipuncture in cats and to validate this simulator using questionnaires answered by undergraduate students and experienced veterinarians. The simulator was developed to provide an experience that was close to reality, including an artificial blood system that flows through the catheter when venipuncture is correctly performed, while at the same time using simple methodology and accessible materials so that it could be reproduced in other universities. The experienced vets agreed (44.4%) or strongly agreed (55.6%) that the simulator was good for venipuncture training, and the most useful feature was the experience of catheter manipulation and fixation on the cat's limb. All the students agreed that the practical class with the simulator was important for learning this skill. Both groups (students and experienced veterinarians) unanimously agreed that it is important to train using a simulator before trying the procedure on a live cat. This simulator offers undergraduate students an alternative way to learn and practice venipuncture in cats helping to reduce the use of live animals in practical classes.

Evaluation of clinical examination location on stress in cats: a randomized crossover trial

OBJECTIVES

The objective of this study was to quantify the effects of owner separation and physical examination location on fear, anxiety and stress (FAS) behavioral indicators in cats.

METHODS

The study was a prospective, non-blinded, randomized, two-period, two-treatment crossover trial. Healthy adult cats presenting for wellness or dental evaluations at a single veterinary teaching hospital received three physical examinations: a baseline assessment (owner present) followed by physical examinations in both a treatment area (owner absent [TAOA]) and an examination room (owner present [EROP]). The physical examination sequence order was randomized. Low-stress handling techniques were used for all examinations. The primary endpoints were heart rate (HR; beats per min [bpm]) and total FAS scores. HR was measured by auscultation, and FAS by five specific behaviors scored as 0/1 and summed for each assessment period.

RESULTS

Twenty-one healthy cats were enrolled. HR measured at entry (baseline) was a significant determinant of subsequent HR readings. HR measured during examinations conducted in both EROP and TAOA were elevated to levels indicative of stress (>180 bpm). HR was significantly higher for TAOA relative to EROP (30 bpm, 95% confidence interval 18-43; P <0.001). Behavioral FAS scores showed no statistically significant effects of sequence or room. FAS scores for TAOA assessments were clinically elevated relative to baseline (1.5 FAS, SE 0.7; P = 0.05); EROP FAS scores relative to baseline did not differ statistically (0.5 units, SE = 0.5; P = 0.43).

CONCLUSIONS AND RELEVANCE

Owner separation coupled with physical examination location can result in clinically significant increases in perceived stress in cats, and compromise vital sign assessments. Whenever possible, physical examinations and procedures should take place with the owner present with separation from unfamiliar dogs and cats.

Development of an ethogram/guide for identifying feline emotions: a new approach to feline interactions and welfare assessment in practice

Background

An accurate assessment of feline behaviour is essential in reducing the risk of handler injury and evaluating/improving feline welfare within veterinary practices. However, inexperience and/or suboptimal education in feline behaviour may cause many veterinary professionals to be ill equipped for this. In addition, busy veterinary professionals may not have time to thoroughly search the literature to remediate this deficiency. Upon searching the literature, terms such as aggression and stress predominate, but these do not completely represent the rich mental lives that cats are now understood to have. Emotions have recently emerged as an alternative approach to animal behaviour/welfare assessment. However, few resources describe how to identify them, and positive emotions are particularly neglected. In addition, no simple, broad, and concise guide to feline emotions currently exists within the research literature. Therefore, this research aimed to develop a straightforward and clear reference guide to feline emotions (ethogram) to aid veterinary professionals in interpreting feline behaviour in practice and for use in veterinary education.

Results

Five primary emotions were identified and defined for domestic species (fear, anger/rage, joy/play, contentment and interest). A feline emotions guide (feline emotions ethogram) was created. Three hundred and seventy-two images were captured of feline behaviours indicative of emotional states. Of these, ten of the best quality and most representative images were selected to illustrate the guide (two of each emotional state). The feline emotions guide and its associated images were subsequently validated by two feline behaviour experts.

Conclusions

Following slight modifications, the emotions definitions yielded during the feline ethogram design process may be transferable to other domestic species. The feline emotions ethogram/guide itself may be particularly helpful for distinguishing immediate motivations and customising patient care within short- term veterinary contexts. Hence, its use may improve feline welfare and feline handling/interactions. However, the guide will need to be reliability tested/ tested in the field and may require adaptation as the feline emotions’ knowledge base grows. In addition, novices may benefit from exposure to more images of feline emotional state, particularly those involving mixed emotions. Freely available online images and videos may be sourced and used to supplement the accompanying image bank.

Efficacy of Oral Sarolaner for the Treatment of Feline Otodectic Mange

Otodectes cynotis is a mite with a cosmopolitan distribution that is the primary agent for the development of otitis externa in feline species. The aim of this study was to evaluate the efficacy of the oral administration of sarolaner for the treatment of feline otodectic mange. We used 20 adult cats of both sexes that were naturally infested with O. cynotis. The mite infestation scoring was performed by video-otoscopy before treatment. The cats were randomized according to the infestation score and divided into two groups (treated and control). The treated group underwent oral administration of sarolaner in a single dose of 2–4 mg/kg. The evaluations were performed by video-otoscopy to evaluate the reduction of infestation score 2, 4, 6, 24 and 48 h and 7, 14, 21 and 28 days after medication. At the end of the study, the cats were sedated to enable the recovery of live and dead mites to determine efficacy. No adverse effects or laboratory changes were observed in these cats. Sarolaner showed 100% efficacy 48 h after treatment. Based on the results, a single oral dose of sarolaner was effective in controlling otodectic mange in naturally infested cats.

Influence of clinical setting and cat characteristics on indirectly measured blood pressure and pulse rate in healthy Birman, Norwegian Forest, and Domestic Shorthair cats

BACKGROUND

Measured indirect blood pressure (BP) results in cats in a clinical environment might be affected by stress and characteristics of the cats.

HYPOTHESIS

To investigate the influence of clinical setting, cat characteristics, and life situation on BP and pulse rate (PR) in healthy cats.

ANIMALS

Ninety-four healthy Domestic Shorthair, Birman and Norwegian Forest cats.

METHODS

Blood pressure measured by high-definition oscillometry in 3 settings: cat placed in its own carrier with veterinarian present; cat placed in carrier with owner alone present; and cat placed on table with veterinarian present. Statistical analyses were performed using mixed linear models.

RESULTS

Systolic BP (SBP) did not differ among settings. Higher mean arterial pressure (MAP), diastolic BP (DBP), and PR were found when measurements were performed with cat placed on table, rather than in carrier. Coefficients of variation (CVs) higher for SBP, MAP, DBP, and PR when measured with cat placed on table than in carrier. Birman cats had lower BP than other breeds. Systolic BP, MAP, DBP, and PR increased with age. Cats allowed outdoors had lower PR than cats living strictly indoors.

CONCLUSION AND CLINICAL IMPORTANCE

No difference in SBP was found among settings, but measuring BP with the cat placed on the examination table gave higher MAP, DBP, PR, and CV than measuring BP with the cat in its carrier. Breed affected BP, with lower BP in Birman cats than other breeds. Blood pressure increased with age. Pulse rate was lower in cats allowed outdoors than cats living strictly indoors.

Effects of Waiting Room and Feline Facial Pheromone Experience on Blood Pressure in Cats

Obtaining accurate blood pressure measurements in cats is challenging due to the stressful nature of clinic visits. The objective of this study was to evaluate the effects of veterinary clinic waiting experiences and a feline pheromone spray on blood pressure in the cat. We hypothesized that reduced stress associated with bypassing the waiting room and use of synthetic feline facial pheromone (FFP) spray would result in lower blood pressure. A 2 × 2 factorial design involved two rooms and two FFP treatments. Thirty-nine healthy adult cats were recruited and were systematically assigned to four treatment combinations administered over four visits in 2016 and 2017. Cats were kept in the hospital waiting room or were taken directly to the exam room, with or without FFP treatment. All cats were then acclimated to the exam room for an additional 10 min, where vocalizations were recorded manually, before blood pressure measurements were collected using Doppler ultrasonography. Data were analyzed using generalized linear mixed models, with room × FFP interaction, visit, sex, and trial year in the model. There was no significant effect of waiting room by FFP interaction on blood pressure (n = 0.95). Mean blood pressure was significantly higher at visit 1 than visits 2 and 4 (P < 0.01), but higher at visit 3 than visit 2 (n = 0.02). Mean blood pressure was higher in males (n = 0.01), and males were more likely to be categorized as borderline hypertensive/hypertensive or severely hypertensive (n = 0.01). Number of vocalizations was significantly associated with waiting room by FFP interactions (P < 0.01), with fewer vocalizations associated with bypassing the waiting room and when FFP was provided. In conclusion, although we found some behavioral evidence supporting stress reduction when feline patients bypass the waiting room and are provided with FFP, these interventions did not result in lower blood pressure in a clinical setting.

2021 AAHA/AAFP Feline Life Stage Guidelines

The guidelines, authored by a Task Force of experts in feline clinical medicine, are an update and extension of the AAFP-AAHA Feline Life Stage Guidelines published in 2010. The guidelines are published simultaneously in the Journal of Feline Medicine and Surgery (volume 23, issue 3, pages 211-233, DOI: 10.1177/1098612X21993657) and the Journal of the American Animal Hospital Association (volume 57, issue 2, pages 51-72, DOI: 10.5326/JAAHA-MS-7189). A noteworthy change from the earlier guidelines is the division of the cat's lifespan into a five-stage grouping with four distinct age-related stages (kitten, young adult, mature adult, and senior) as well as an end-of-life stage, instead of the previous six. This simplified grouping is consistent with how pet owners generally perceive their cat's maturation and aging process, and provides a readily understood basis for an evolving, individualized, lifelong feline healthcare strategy. The guidelines include a comprehensive table on the components of a feline wellness visit that provides a framework for systematically implementing an individualized life stage approach to feline healthcare. Included are recommendations for managing the most critical health-related factors in relation to a cat's life stage. These recommendations are further explained in the following categories: behavior and environmental needs; elimination; life stage nutrition and weight management; oral health; parasite control; vaccination; zoonoses and human safety; and recommended diagnostics based on life stage. A discussion on overcoming barriers to veterinary visits by cat owners offers practical advice on one of the most challenging aspects of delivering regular feline healthcare.

The impact of a stress-reducing protocol on the quality of pre-anaesthesia in cats

INTRODUCTION

Transport to the clinic is a major source of stress for cats. The process involves being put into a carrier, driven in a car and handled. Cats are therefore removed from the safe-haven of their territory and experience many stressful stimuli and interactions.

METHODS

In the present study, 31 cats were transported to the clinic following a low-stress transport protocol and compared with a control group of 36 cats whose owners did not follow the protocol. This protocol involved preparing a cat carrier basket with F3 pheromone and keeping it covered and stable during the car journey from the home to the clinic. Pre-anaesthesia information was recorded for cardiac rate, respiratory rate, tolerance to handling, time for sedation to be achieved and dose of propofol required for induction and endotracheal intubation.

RESULTS

The group exposed to the low-stress transport protocol took less time to reach sedation and needed a lower dose of propofol for induction than the control group.

CONCLUSION

These results suggest that, in cats, pre-anaesthetic and induction requirements are influenced by lower-stress transport and handling.
