A technology-enhanced weight-loss program in multiple-cat households: a randomized controlled trial

Identifying the target population and preventive strategies to combat feline obesity

Feline obesity continues to be a priority health and welfare issue. Most research surrounding obesity currently focuses on obesity treatment. However, treatment for feline obesity is slow, often unsuccessful and not without consequences. Identifying high-risk populations for obesity onset is crucial for developing and implementing preventive strategies. This review identifies post-gonadectomy kittens aged 5-12 months as the primary target population for obesity prevention in domestic cats and highlights dietary and feeding management strategies to be implemented for obesity prevention.

The standards of reporting trials in pets (PetSORT): Explanation and elaboration

Well-designed randomized controlled trials (RCTs) provide the best evidence of the primary research designs for evaluating the effectiveness of interventions. However, if RCTs are incompletely reported, the methodological rigor with which they were conducted cannot be reliably evaluated and it may not be possible to replicate the intervention. Missing information also may limit the reader's ability to evaluate the external validity of a trial. Reporting guidelines are available for clinical trials in human healthcare (CONSORT), livestock populations (REFLECT), and preclinical experimental research involving animals (ARRIVE 2.0). The PetSORT guidelines complement these existing guidelines, providing recommendations for reporting controlled trials in pet dogs and cats. The rationale and scientific background are explained for each of the 25 items in the PetSORT reporting recommendations checklist, with examples from well-reported trials.

Survey of Belgian owners' perspectives on quality of life and difficulties during a weight-loss programme in obese cats

OBJECTIVES

The aims of this study were to determine owners' perception of their cats' quality of life (QoL), and whether there is a correlation with weight-loss variables, as well as to identify the main difficulties owners encounter during controlled weight loss in their obese cats.

METHODS

The study was carried out as an e-questionnaire survey addressed to owners of cats starting a weight-loss programme. The e-questionnaire was provided at a single time point after the conclusion of the study (24 weeks).

RESULTS

Nineteen completed questionnaires were included. Eighteen cats had a lower weight at the end of the weight-loss period, two of which had successfully reached their target weight. Mean weight loss was 13.84% body weight at a rate of 0.53% weight loss/week. Although the perceived QoL was not correlated with weight-loss variables (P >0.05), it increased over time, even in cats that did not reach their target weight, and was statistically correlated with increased activity (r = 0.73; P <0.01), mobility (r = 0.78; P <0.01) and play time (r = 0.61; P <0.01). The main difficulties encountered by owners were not giving (32%) or permitting the cat to eat extra food (26%). The main presumed difficulty for the cat was having its food decreased over time (53%). Most owners considered their cats happy (42%) and quite happy (53%) during the study, and no statistically significant correlations were found between the weight loss, food-seeking behaviour and stress parameters (P >0.05).

CONCLUSIONS AND RELEVANCE

Although several difficulties were encountered throughout the study, increased QoL and energy levels in their cats were noticed by owners. A positive perspective on weight-loss programmes is important to keep owners motivated and achieve the target weight in their cats. Furthermore, this survey provides insights into the perceived difficulties of weight-loss regimens in cats.

Evaluation of a pet-separating automatic feeder and high-frequency meal feeding for weight loss in multi-cat households

OBJECTIVES

The objectives of this study were two-fold: (1) to determine if a feeder system providing individualized food access and automatic dispensing of meals makes weight-loss programs in multi-cat homes easier for cat owners; and (2) to assess if feeding six meals daily reduces food-seeking behavior and increases calorie requirements vs two meals per day.

METHODS

Adult cats with body condition scores (BCSs) of 7/9 or greater underwent a weight-loss plan for up to 6 months using a traditional feeding bowl with two meals per day (B2) or an automatic feeder with two meals (A2) or six meals (A6) per day. Cats were weighed at weeks 0, 2, 4, 6, 10, 14, 18, 22 and 26 and food intake was adjusted to maintain weight-loss rates between 0.5% and 1.5% body weight per week. Owner questionnaires were completed at each study visit.

RESULTS

Twenty-three cats were included in the study. Cats fed from the automatic feeders were more likely to reach ideal body condition (P = 0.006), with 83.2% of cats in A6, 40% of cats in A2 and no cats in B2 achieving a BCS of ⩽6/9. Owners of cats fed from automatic feeders reported the weight-loss plan was easier vs owners of cats fed from bowls (P = 0.01). Owners using the automatic feeders also reported fewer incidences of certain food-seeking behaviors. Neither percent body weight lost per week nor calorie intake per kg differed between groups.

CONCLUSIONS AND RELEVANCE

Feeding six instead of two meals daily did not result in faster rates of weight loss or the need to increase calorie intake to maintain appropriate rates of weight loss. However, use of an automatic feeder that provided separated, portioned meal feeding made the weight-loss program easier, reduced food-seeking behaviors and improved the overall success of the weight-loss plan.
