Abstract
Ferrets are susceptible to many disorders affecting the respiratory tract including both primary diseases and diseases of other body systems secondarily affecting the respiratory tract. Some primary respiratory diseases are shared with other mammal species including humans; potentially zoonotic diseases include important pathogens such as influenza and SARS-CoV-2. Other diseases include infections (bacterial, parasitic, and fungal) and neoplasia. A thorough workup is important to identify exact causes in order to formulate a treatment plan. Infectious diseases include bacterial, fungal, parasitic, and viral.

Abstract
Marsupial reproduction differs significantly in anatomy and physiology from that of placental mammals. The gastrointestinal and urogenital tracts empty into a cloaca. Reproductive parameters include gestation and pouch time, as the fetus develops outside of the uterus. Captive marsupials discussed include sugar gliders), short-tailed opossums, Virginia opossums, and Tammar and Bennett's wallabies. Common disease conditions include joey eviction, pouch infections, mastitis, metritis, prostatitis, penile necrosis, and neoplasia. Common surgeries include penile amputation, castration, and ovario-vaginal-hysterectomy or ovario-hysterectomy. Therapeutics used for these conditions are presented.

Abstract
Unusual mammalian species such as the hedgehog, sugar glider, and miniature pig are encountered with increasing frequency in exotic companion medicine. Disease of the oral cavity can occur in any species; although occasionally encountered in exotic mammalian species, it is rarely described in the literature. Anatomy and dentition vary significantly; diagnosis and treatment are often extrapolated from that known in other species. The best-documented disease of the oral cavity in this group of species is oral neoplasia in the hedgehog.

Abstract
The level of care for smaller companion mammals has increased significantly during the past few years. Today, exotic companion mammals are acknowledged as a specific area of zoologic medicine. Owner demands for a higher level of care is increasing dramatically. Because most of these patients are small (less than 2 kg), this represents a great challenge, in particular for the field of diagnostic imaging. This article reviews the 5 main diagnostic imaging modalities currently available for investigation of the respiratory system of exotic companion mammals: radiography, ultrasonography, endoscopy, computed tomography, and magnetic resonance.

Abstract
The average life span reported in laboratory and lay literature for the domestic rabbit is 5 to 10 years. The author and other veterinarians are now regularly seeing rabbits living to 9 or 10 years, the oldest reported in the author's practice being 14 years. Rabbits are herbivorous prey species with continually growing (elodont) teeth. This feature allows the geriatric rabbit to possess teeth that are essentially "new", a distinct advantage over geriatric carnivores. Expanded longevity, while generally desirable, necessarily accompanies an increase in geriatric disorders. This article examines the spectrum of disease that can affect the geriatric rabbit as well as crucial factors concerning the clinical management of the animal up to the end of its life. An improved understanding of geriatric disorders in pet rabbits allows early recognition and the opportunity to improve quality of life.

Abstract
Bacterial disease is common in pet rabbits; parasitic disease occurs as well but at a much lower frequency. Of these, bacterial diseases of the respiratory tract and dental structures are seen most commonly in practice. Successful treatment depends on positive diagnosis of the disease process and causative agent. This article focuses on the more common bacterial and parasitic diseases encountered in clinical practice.

Abstract
Less common exotic pet mammals are gaining in popularity. The Australian Sugar Glider, African Hedgehog, and prairie dog are seen regularly in exotic animal practices. They are subject to the same types of medical emergencies as more traditional pets, with the unfortunate addition of all too common underlying nutritional and husbandry-related disorders. Emergency stabilization and critical care are important first steps before collection of diagnostic test samples and administration of definitive medical care.

Abstract
An approximately 3-year-old adult male zebra finch (Taeniopygia guttata) was diagnosed with malignant melanoma. The large darkly pigmented tumor was located in the coelom, extended from the apex of the heart to the cloaca, and was adherent to the intestines and the ventriculus. Dark small masses (likely metastases) were observed in the lungs. Cytologically, the neoplasm consisted mainly of round to oval cells with brown or pale blue to blue-brown pigment. Lesser numbers of cells were stellate to dendritic with abundant amounts of brown pigment granules or were markedly pleomorphic with variable amounts of pigment. Histologically, the tumor consisted of dense sheets and aggregates of infiltrative melanocytes that were negative for S-100 and Melan A. A few cells were consistent with "signet-ring" melanocytes. Melanocytes examined by electron microscopy contained typical structures, mainly premelanosomes and melanosomes, of this cell type. However, melanocytes with marked pleomorphism also contained intracytoplasmic aggregates of filaments, consistent with previously reported ultrastructural findings in signet-ring or rhabdoid melanoma of nonavian species.

Abstract
Although psittacine species represent the majority of avian patients seen in most exotic animal practices, nonpsittacine species such as passerines and galliformes may be presented as pets, as members of zoo collections, or as injured or ill wildlife. Many features of handling, restraint, sample collection, medicine, and surgery are similar in psittacine and nonpsittacine species. In many cases, the equipment required will be similar as well, with a few modifications.

Abstract
1. Total lipids were extracted from digesta obtained from the rumen, abomasum and upper small intestine (jejunum) of each of four slaughtered sheep. The lipids were fractionated into unesterified fatty acids, neutral lipids and phospholipids and the proportional contribution of each fraction to the total fatty acids was determined.2. The contribution made by phospholipids to the total fatty acids in the digesta showed a marked increase in the samples from the small intestine compared with those from the rumen and abomasum. This increase was apparently due to the presence of biliary phospholipids.3. Total lipids and conjugated bile acids were extracted from sheep bile, the lipids were fractionated and their fatty-acid composition was determined. Phospholipids predominated and these consisted mainly of phosphatidylcholine, together with some lysophosphatidylcholine.4. Both phospholipids contained significant amounts of unsaturated C18components which could account, at least in part, for the previously reported increament to the proportion of these acids in the digesta when it enters the upper jejunum.5. The overall fatty acid compositions of the two biliary phospholipids were very similar and, in common with other naturally occurring phosphatidylcholines, the fatty acids present in position 2 of the phosphatidylcholine of bile were found to consist almost entirely of unsaturated components.6. Total lipids and conjugated bile acids were extracted from samples of digesta obtained from three sheep with cannulas in different positions in the jejunum. Analysis of the lipids indicated that biliary phospholipids, in particular phosphatidylcholine, underwent progressive hydrolysis in the intestinal lumen.7. The distribution of conjugated bile acids, unesterified fatty acids and phospholipids between the solid (particulate) and liquid (micellar) phases of the intestinal digesta was determined. These chyme constituents were, for the most part, associated with the particulate matter and thus, at any given time, it appears that only a small fraction of the total fatty acids is available for absorption in micellar form. It is suggested that the micellar solubilization of fatty acids may be facilitated by the presence of lysophosphatidylcholine.

Abstract
1. Three sheep, each of which was fitted with a rumen cannula and with two pairs of reentrant cannulas in different parts of the small intestine, were used in this study. They were fed on dried grass cubes or hay plus linseed meal and oats: an aqueous solution of polyethylene glycol (PEG) was infused continuously into the rumen.2. Total lipids were extracted from samples of the chyme entering and leaving the different lengths of the small intestine embraced by the respective cannulas. The lipids were fractionated into unesterified fatty acids, neutral lipids and phospholipids and the contribution of each fraction to the total fatty acids was determined. The samples were also analysed for their PEG content, thus affording an index of the extent to which water had been absorbed from each particular length of intestine.3. From the above findings and a knowledge of the flow-rate of the digesta, the uptake of unesterified fatty acids and the degree of dissimilation or uptake, or of both, of esterified fatty acids was calculated.4. The results indicated that, by the time the digesta reached the ileum (i.e. the distal half of the small intestine), the uptake of fatty acids was almost complete, as was also the hydrolytic release of esterified fatty acids.5. Though there were no gross differences in the overall composition of the unesterified and esterified fatty acids in different parts of the small intestine, it appeared that C18mono-unsaturated acid, the principal unsaturated unesterified acid, was absorbed somewhat more efficiently than were the major saturated acids (palmitic acid and stearic acid).
