Ocular problems are common in both laboratory and pet rabbits ( Oryctolagus cuniculus), and disease of the nasolacrimal duct is one of the most frequently reported ocular diseases in rabbits. This review article features a brief video illustrating this clinical technique plus step-by-step guidance as well as clinically relevant anatomy and recommendations for diagnosis and treatment of dacryocystitis.
Both males and female pigs possess modified upper and lower canine teeth or tusks, however, the tusks of the male retain an open root that allows these teeth to grow throughout life. Tusks can become long and extremely sharp and trims may be necessary to prevent injury to humans, other animals, household furniture, flooring, or even the pig itself. This brief article discusses relevant anatomy, equipment needed, potential complications, sedation, and step-by-step advice for successfully completing this clinical technique.
The postmortem exam is a key diagnostic tool in understanding the reasons for a snake’s morbidity and mortality. Necropsies can provide valuable information to provide a risk assessment for other animals in a population or collection and can help provide closure for a grieving owner. This manuscript reviews the snake necropsy in a systemic, thorough manner, describing normal anatomy and proper collection technique from head to tail.

Dr. Renée Schott presented a live, interactive webinar on reptile wildlife euthanasia techniques. View the RACE-approved webinar recording today. Wildlife often present to veterinarians and wildlife rehabilitators with conditions that warrant euthanasia. It can be difficult, however, to apply mammalian methods of euthanasia to species with unique physiology such as reptiles. This interactive presentation will use cases to discuss practical euthanasia methods for reptiles and the physiology behind these methods. Emphasis will be placed on freshwater turtles as these represent some physiological extremes.
Dr. Todd E. Driggers presented this live webinar event on Flight Mechanics, Parrot Welfare, and Ethical Concerns. View the video recording, then take the brief post-test to earn 1 hour of continuing education credit. Feather trimming birds in captivity has been a common practice performed for many reasons, including fear of loss, safety, and the ability to control and tame. If the gold standard for animal welfare is freedom and feather destructive behavior is a reliable indicator of scientifically studied animal welfare, feather trimming impacts how the animal feels, functions, and prohibits natural responses to positive or aversive stimuli. Perhaps it is time to reflect on the benefits and risks of feather trims through the lens of animal welfare. At a minimum, the degrees of severity of the current techniques need redressing when we consider the experience of the bird.
Snakes are members of the class Reptilia, order Squamata, and suborder Serpentes. There are over 3,500 species of snakes in the world, however, for the most part, the anatomy of the snake is consistent across species.

Blood collection in miniature pigs can be a challenge. Peripheral veins are not readily accessible and some vessels, such as the auricular vein, are inadequate for obtaining sufficient volumes. The radial vein is located along the medial aspect of the forelimb. This vessel is relatively straight and generally superficial.
The term “miniature pig” is used to describe a variety of smaller pig breeds as well as crossbreeds. There are at least 14 recognized breeds of miniature pigs, including the Vietnamese potbellied pig, the Juliana pig, the KuneKune, and others. This information sheet reviews natural history and taxonomy, as well as a number of clinically relevant information including (but not limited to) diet, housing, behavior, normal physiologic data and anatomy, restraint, preventive medicine, zoonoses, and important medical conditions seen in the mini pig.

Reptile reproduction can be a confusing topic due to the variety of normal reproductive strategies found throughout different reptile species. Nevertheless it important to understand normal reproductive processes to correctly approach some commonly seen problems. The recording of this R.A.C.E.-approved, web-based seminar discusses normal reproductive strategies of reptiles, including important reproductive anatomy and physiology. Three clinically important conditions, pre-ovulatory or follicular stasis, post-ovulatory dystocia, and cloacal prolapse, are also explored in detail.
The Virginia opossum is the only marsupial native to North America. This New World species is correctly called an “opossum” as opposed to the Old World “possum”. This information sheet reviews natural history, conservation status, and taxonomy, as well as a number of clinically relevant information including (but not limited to) diet, housing, behavior, normal physiologic data and anatomy, restraint, preventive medicine, zoonoses, and important medical conditions seen in the opossum.
Reptile dentition tends to be relatively uniform with a simple, conical shape. Most reptile teeth are loosely attached with the dental attachment most superficial in acrodontic species. Tooth loss and replacement is a normal occurrence in reptile species with pleurodont dentition, which includes snakes, and many lizards. Take special care when handling reptiles with acrodont dentition as teeth will not be replaced when infected or fractured. Additionally, periodontal disease is common in captive lizards with acrodont dentition such as bearded dragons and chameleons. Periodontal disease is an insidious condition. As plaque formation builds and gingivitis worsens, many reptiles will continue to eat. The owner may not observe problems until disease is quite advanced. Feeding lizards an unnatural, soft diet is believed to promote plaque development and the development of periodontal disease.
The guinea pig is a popular companion animal and a common research model. Guinea pigs are useful in reproductive studies because they share many reproductive traits with human beings.

This post also touches on specialized anatomic features unique to fruit pigeons before summarizing some features of the columbid integumentary system, musculoskeletal system, and urogenital tract.
All raptors consume a meat-based diet ranging from the specialist diet of the fish-eating osprey (Pandion haliaetus) to a generalist diet that can include insects, mammals, birds, reptiles, amphibians, and even carrion. Other than poultry, the exact nutritional requirements of birds are unknown, however the natural raptor diet is always relatively high in protein and fat and low in carbohydrates. Whole prey diets have a calcium/phosphorus ratio of 1.5:1 as the bird actually consumes the bones as well as the meat…
Raptors are a diverse group of birds consisting of order Strigiformes or owls and diurnal birds of prey such as falcons, hawks, and eagles. Order Falconiformes, traditionally considered a broadly defined, polyphyletic group, has recently been divided into two orders with only family Falconidae (falcons and caracaras) remaining in Falconiformes. Other diurnal raptors belong to order Accipitriformes …

Twitter topics ranged from turtle and tortoise ophthalmic anatomy to chelonian clinical problems like blepharedema, commonly associated with hypovitaminosis A in aquatic turtles.
Calcium is the most abundant mineral in the body, and the majority of total body calcium is found within bones and teeth. Most mammals make only one or two sets of teeth in a lifetime, however rabbit teeth continually grow throughout their lifetime. This continual tooth eruption plays an important role in the rabbit’s long-term calcium needs.
Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs) that comprise a small percentage of dietary lipids ingested by humans and animals. The name “omega-3” refers to the location of the double bond closest to the methyl end of the hydrocarbon chain, and may be alternatively referred to as “n-3” in the literature. Chief among the omega-3 fatty acids is…
Fennec foxes (Vulpes zerda) are the smallest members of Order Carnivora. Females or “vixens” weigh approximately 0.8 kg. Adult males or “reynards” reach up to 1.5 kg and stand 18 -22 cm at the shoulder. Its most distinctive feature is characteristic large pinnae, which function to dissipate heat and enhance hearing. Fennec foxes are highly specialized to desert life and found almost exclusively in arid, sandy regions. Densest populations are found in the central Sahara desert region of North Africa.

A bird is a wing guided by an eye… Rochon-Duvigneaud: Lex Yeux et La Vision Des Vertebres
The avian eye is a large structure that takes up a significant portion of cranial mass. Raptors depend heavily on vision in order to compete successfully for survival. The posterior aspect of the eye fits snugly within the large bony orbit. The globes are separated by a thin interorbital septum, which measures significantly less than 1 mm in some areas…
The avian patient poses special challenges for delivery of injectable medications. Although the techniques involved are not unique to birds, special knowledge of avian anatomy as well as delicate, proficient technical skills are required. Depending on the species, the individual, and the clinical situation, injections can be delivered by intramuscular, intravenous, intraosseous, subcutaneous, intratracheal, or intracoelomic routes. Parenteral drug administration provides the advantage of delivering a precise dose when a rapid therapeutic response is necessary. Disadvantages include stress as well as the potential irritation or pathology that can occur at the injection site.
Diarrhea is a common clinical presentation in avian medicine. Diarrhea may be caused by a variety of conditions, however it is particularly important for the practitioner to understand the anatomy and diseases of the avian gastrointestinal tract and associated organs.
The most widespread mineral in the body, calcium is required for normal metabolism and bone mineralization.
Calcium homeostasis is under the control of calcitonin, which is produced by the ultimobranchial gland, vitamin D, and parathyroid hormone. In laying hens, most dietary calcium is used for egg production. Rising estrogen levels promote increased intake of calcium supplements like cuttlefish bone and calcium-rich foods, however the quantity of calcium ingested daily is insufficient for the massive deposition of calcium required for eggshell calcification.

Herbivore nutrition separates animals into two main categories, depending on where food particles are broken down and fermented prior to absorption. The categories are foregut and hindgut fermenters, with the hindgut group being broken down into colonic and cecal fermenters.
Air sac cannulas are routinely used to ventilate birds by a route other than endotracheal intubation. Air sac tubes are used for oxygenation and anesthesia, especially during surgery of the head or trachea where tracheal intubation would be cumbersome. In addition, air sac cannulas provide a means to medicate air sacs directly, and they are also used to aid dyspneic birds with tracheosyringeal obstruction from foreign bodies, granulomas, or tumors.
The ferret is a carnivore with a short, simple gastrointestinal tract and a relatively rapid gastrointestinal transit time. Diarrhea is the most common clinical sign in ferrets with gastrointestinal disease, with the exception of gastrointestinal foreign bodies where anorexia and weight loss are the primary presenting complaints.
Primarily a disease of captive reptiles, dysecdysis is sporadically seen in free-ranging reptiles. Among captive reptiles, difficult sheds are most common in those with a complete shedding cycle: snakes and some geckos such as the leopard gecko and African fat-tailed gecko. Some skinks with relatively tiny digits, are prone to retaining shed skin on the digits.
External reproductive anatomy is obvious in some adult small mammals such as the ferret, sugar glider, hedgehog, rat, guinea pig, and hamster. Gender determination or sexing can be challenging in some species like the chinchilla, and in many neonatal rodents. In these cases, reliance on anogenital distance or the distance between the rectum and the urogenital region is considered best practice.
The average small animal veterinarian may easily become comfortable with ferrets. Ferrets are hardy and relatively stoic, and as members of the order Carnivora, ferrets are predator species that approach the world in a manner similar to cats and dogs. A relatively small number of medical problems are seen very commonly in ferrets. Careful study of these conditions and attention to the unique aspects of ferret anatomy and behavior will prepare the veterinarian for basic emergency care of the ferret.

Acquired dental disease is an important problem in pet rabbits and rodents. Clinical management of dental disease is complex, frequently involving invasive technical procedures, therefore it is preferable to promote dental health, rather than treating dental disease. What are five things you can do to promote dental health in small herbivores?
Most small herbivores like the rabbit, guinea pig, and chinchilla possess a simple, non-compartmentalized stomach paired with a large cecum and colon. To feed the small herbivore gastrointestinal tract, provide insoluble dietary fiber to stimulate gut motility and maintain gastrointestinal health. A balanced small herbivore diet contains adequate fiber (minimum 25%), minimal starch, and moderate protein levels. Among small herbivorous non-ruminants, the gastrointestinal tract of the rabbit is the most specialized and this manuscript will focus on unique features of this species’ anatomy and physiology.

Free-ranging sugar gliders live in the treetops and glide from tree to tree using their patagium like a kite and their tail as a rudder to control the direction of flight. The patagium is a furred membrane of skin or gliding membrane that stretches between the forelimbs and hind legs. These skin folds are extensions of the lateral body wall. When the glider is at rest, this excess skin appears as a rippled border along the sides. During a glide, the skin spreads out to form a rectangle…

Red-eared sliders are native to the eastern and central United States river valleys. Most pet sliders are captive bred and hatched. Red-eared sliders are hardy and outgoing. Although pretty and personable as pets, red-eared sliders occupy a niche of dark history in herpetoculture, first as transmitters of Salmonella bacteria to small children, second as an invasive species that have disturbed ecosystems throughout the waterways of the world. The former problem is the result of husbandry and marketing practices of large-scale commercial producers; the latter due to illegal release of unwanted pets.
The panther chameleon is indigenous to Madagascar. Most specimens in the pet trade used to be wild caught, however with changes in Madagascar’s export regulations and better understanding of the care of these exquisite lizards, most are now captive-bred.
Leopard geckos are originally from the grassland and desert regions of India and Pakistan. The vast majority of pets are captive bred and hatched. Leopard geckos are nocturnal, terrestrial, long-lived lizards that make excellent pets.
