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.
Guinea pigs are small, docile rodents, that must be approached with great care. Accurate evaluation of patient health status requires a thorough history, careful visual examination, and a detailed physical examination. Like most prey species, the guinea pig frequently hides signs of pain and illness. To improve clinical success, take measures to minimize stress by maintaining the animal in a quiet exam room and approaching the patient in a slow, quiet manner. The hospitalized guinea pig can also benefit greatly from the presence of a bonded cage mate. Monitor appetite and eliminations carefully in the guinea pig, and offer the same diet as fed in the patient’s home whenever possible as guinea pigs establish strong food preferences early in life.
Diagnostic and therapeutic procedures cannot be administered until you and your staff can safely handle and restrain the lizard patient. This article reviews patient transport and defense mechanisms of the lizard, including tail autotomy, as well as protective gear and restraint techniques.
Diagnostic and therapeutic procedures cannot be administered until you and your staff can safely handle and restrain the turtle or tortoise patient. Many chelonian patients presented to the veterinary hospital are ill and therefore their temperament and strength level can be reduced. Normal, healthy chelonians tend to be bright, alert and very strong, making them extremely challenging to restrain. Gaining control of the head can be particularly difficult, however multiple techniques have been described.
Veterinary practices are often more hesitant to deal with snakes than with other pet reptiles, yet for the most part snakes are probably the easiest reptile patients to capture and restrain in clinical practice. This article reviews the defense mechanisms of snakes as well as transport, restraint techniques, and potential complications.
Welcome to LafeberVet’s Basic Rabbit Care Teaching Module! Upon completion of this learning aid, the participant will have a basic clinical understanding of what defines a rabbit, common rabbit breeds, anatomy and physiology, behavior, restraint and handling, as well as husbandry needs.
With the help of a handy infographic, this client education handout reviews the basics of a good rabbit diet as well as housing, including “bunny proofing”, and handling.
Exotic small mammals can be challenging to safely induce, maintain and recover from general anesthesia. View the recording of this AAVSB R.A.C.E.-approved webinar, which explores clinical anesthesia in exotic companion mammals from patient assessment and anesthetic induction to monitoring and recovery. The use of common premedications, induction agents, maintenance drugs, and post-operative analgesics will be compared and contrasted in exotic companion mammals. Multimodal anesthetic techniques, such as epidural anesthesia and constant rate infusions, will also be discussed. After reviewing the recording, take the brief post-test to earn 1 hour of continuing education credit.
Authored by experts in the field: Terry Norton, DACZM, Director/Founder of the Georgia Sea Turtle Center, and Jeanette Wyneken, PhD, this article is part of a unique series on sea turtle veterinary medicine and wildlife rehabilitation. Physical examination of the head and neck are covered including eyes, adnexa, ears, nares, beak, the oral exam, throat, and cervical vertebrae. Normal findings that reflect adaptations to a marine lifestyle are reviewed and unique findings seen in green (Chelonia mydas), flatback (Natator depressus), hawksbill (Eretmochelys imbricata), Kemp’s ridley (Lepidochelys kempi), leatherback (Dermochelys coriacea), loggerhead (Caretta caretta), and olive ridley (Lepidochelys olivacea) turtles are discussed.

Behavior is the most direct tool a wild bird has to respond to its environment, and it ultimately determines whether it survives and breeds in its natural environment. There are two functional categories of avian behaviors: self-maintenance behaviors and social behaviors.
Exotic animal medicine requires a delicate balance between medical concepts true for all living creatures (“one medicine”) and species-specific information and this is true for lizards.
Lizard behavior varies with the species, however the normal lizard tends to be alert, responsive, and curious. Some species, like the bearded dragon and leopard gecko tend to be particularly active and animated while most chameleons are more…
The lethargic, weak chelonian may exhibit a lack of carpal or truncal lift. It may sit flat on the exam table instead of lifting up on all four feet, and it may not be able to retract its head into the shell with the expected degree of strength. It can be challenging to…
Restraint collar devices are also referred to as ‘neck collars’ or ‘safety collars’. The most common restraint collar is the Elizabethan collar (or e-collar). Many different manufacturers sell e-collars and modified e-collars designed for different species and for specific purposes. Restraint collars are widely used to prevent undesirable behaviors and self-injury. Clinically, veterinarians have used restraint collars in birds to prevent self-mutilation or self-trauma and to prevent animals from removing intravenous catheters, bandages, and other external devices.
Manual restraint of exotic companion mammals is a challenging but necessary part of veterinary practice. In the recording of this R.A.C.E.-approved webinar, Ms. McClellan reviews the approach to predator and prey species as well as the principles of capture and handling of several species of small exotic companion animals in a hospital setting including from rabbits, guinea pigs, and chinchillas to small rodents, hedgehogs, and sugar gliders.

Key parts of the exam will vary, but generally include a body weight in grams, the oropharynx, crop, sternum, coelom, and vent. The fundus should be routinely evaluated in trauma patients…
According to the Humane Society of the United States,17 deaths and many more injuries have been related to large constrictors since 1978. Given the tens of thousands of large constrictors sold, the incidence of fatalities and injuries is relatively low, however every incident—including the death of four babies in their cribs and three additional children—is particularly tragic since these cases are completely preventable. In this client education handout, safety tips involving snake feeding, housing, and behavior are discussed.
The veiled chameleon is indigenous to Yemen, in the southwestern region of the Saudi Arabian peninsula. This species is found in extreme environments ranging from arid desert to seasonal “wadis” or streams that form in the desert after rain. Pets may be captive bred or wild caught and imported.
Uromastyx spp. are also known as dabb lizards or spiny-tailed lizards. This latter name comes from its thick, short tail covered with large, spiny scales. The Moroccans spiny-tailed lizard or agama is native to the deserts of northern Africa. Colorful specimens of the pet trade are often captured from Morocco, Algeria, Tunisia, and Mauritania. The range of the ornate spiny-tailed agama is restricted to the Sinai Peninsula in Egypt. Wild-caught animals are more common than captive bred in the pet trade, this is particularly true for the…
The Savannah monitor is native to the savannahs of eastern and southern Africa. In the wild these monitors are scavengers covering large distances as they search for small prey items. Savannah monitors in the pet trade are…
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.
There are several species of kingsnake and their habitat and range vary. The Eastern kingsnake is found in humid forests of the eastern seaboard states and as far west as the Appalachians and Alabama. The California kingsnake is native to desert, arid grassland, and rocky hillsides of Baja Mexico and the western United States. Pets may be bred in captivity or wild-caught. Kingsnakes are fairly docile, medium-sized, hardy reptiles, that make…
Jackson’s chameleons comprise three distinct subspecies native to the montane regions of Kenya. Large feral populations are found in Hawaii where specimens are often caught for the pet trade. Small numbers are also captive-bred.
The green iguana is native to the tropical rain forests of Latin America. Most pet iguanas are raised on farms in El Salvador and Costa Rica although wild-caught imports and domestically captive-bred lizards are also available.
Native to the tropical rain forests of Central and South America, tiny poison dart frogs secrete lipophilic alkaloid toxins through their skin. These toxins serve as a chemical defense against predation. Some native tribes are renowned for dipping arrow tips in the toxins from these frogs. These beautiful, active frogs are outgoing and diurnal, making excellent “look but don’t touch” pets. Many but not all specimens in the pet trade today are captive bred. Frogs bred for several generations in captivity fail to synthesize…
The corn snake is also known as the red rat snake. Corn snakes are found in woodland and forest regions of the southeastern and central United States as far west as Kentucky and Louisiana and as far south as Mexico. Pets may be wild-caught but most are captive bred and many color morphs are now available in the pet trade.
Green water dragons are native to tropical forests or areas near the river’s edge in southeast Asia. Pets are primarily wild-caught and wild-caught adults can have a difficult time adjusting to captivity. Water dragons are beautiful lizards that make stunning display animals in naturalistic vivaria, however these lizards are inexpensive and imported in large numbers. These flighty lizards then end up in private homes where…
The African bullfrog lives in a variety of arid and semiarid habitats in central and southern Africa. This frog has long ridges on the skin of its back and a huge head.
The pet trade is supplied by captive-bred and wild-caught specimens. African bullfrogs are often called “Pixie” frogs (derived from their genus, not their size). It is theorized that a number of different subspecies or species are now sold in the trade as African bullfrogs.
The group of snakes called “boas” consists of over 40 species. Most popular pet boas are New World species, however boas are also found in Africa and Asia. Most boas live in environments that range from tropical rain forest to dry woodland and scrub forest. Sand boas (Gongylophis spp.) may be found in desert and savannah land and Rosy boas (Lichanura spp.) live in dry, rocky habitats.
Pythons are found in Africa, Australia, and Asia under conditions that range from rain forest to desert. Some species are primarily ground dwellers, but most can be found in bushes and trees. The larger species are often found near water and are strong swimmers.
Pet boas and pythons may be…
The blue-tongued skinks are represented by a variety of species, subspecies and races native to Australia, New Guinea and Indonesia. Two of the more common varieties in the pet trade are the northern, Tiliqua scincoides intermedia, and Irian Jaya, an undescribed T. scincoides. These ground-dwelling diurnal skinks have tiny legs and feet, heavy bodies, and a large, blue tongue that can be bared as a warning to potential enemies.
Some blue-tongued skinks are domestically bred, however many are imported from Indonesia and New Guinea.
Native to the central deserts of Australia, the Bearded dragon’s name comes from its practice of extending the flap of skin under the jaw or “beard” in a defensive posture.
The most common pet mouse is the standard white laboratory mouse, although pet mice are not as inbred as some strains of lab mice.
Hamsters are short, stocky rodents with an abundance of loose skin. Today’s pet or laboratory hamster, known as the Syrian hamster, was bred from a small group of hamsters removed from a burrow near Syria in 1930 as well as 11 more collected in 1971 and three in 1978.
Gerbils are omnivores. In the wild the diet consists of grasses and seeds with small amounts of insects. A captive diet consists of a high-quality pellet supplemented with…
Degus, also known as brush-tailed or trumpet-tailed rats, are natives of central Chilean open scrubland where they are routinely exposed to droughts. Degus survive on very poor diets in the wild.
Wild degus feed on grasses, seeds, cactus fruits, tubers, and local crops. The captive diet should consist of…
Cottontail rabbits eat a wide variety of plant foods including grasses, sedges, sprouts, leaves, fruits, buds, and bark. During the summer months, cottontails primarily eat grasses, legumes, succulent annuals, weeds, as well as the occasional garden vegetable. The winter diet includes small grains, as well as twigs, bark, and buds of shrubs and trees. Favorite food items often include white and crimson clover, Bahia grass, and green succulent vegetation like alfalfa, wheat, barley, ryegrass, and winter peas.
A captive diet frequently consists of…

The long-tailed chinchilla is native to the mountains and foothills of the Andes Mountains in South America. These rodents are known for their large ears and soft, luxurious fur. Chinchillas make charming pets, but they are naturally skittish and are not considered a good choice for small children because of their delicate bones and their hyperactive natures. Most pet chinchillas live 6-10 years.
This client education handout reviews basic husbandry recommendations, including diet, housing, dust bathing, exercise, as well as handling and behavior.
At the Ontario Turtle Conservation Centre, previously the Kawartha Turtle Trauma Centre, we encourage private practices, emergency clinics, and rehabilitation centers to aid in the initial treatment of these injured turtles. We admit turtles from across the province, and it is extremely beneficial to the turtle to get immediate care locally before transfer. Snapping turtles are incredible in their ability to heal (albeit slowly!) and we cannot stress enough that the injuries can appear horrific, and yet can go on to heal, with subsequent release of the turtle back into the wild…
Grooming in the bird can refer to clipping wing feathers, trimming nails, and smoothing and/or trimming the beak. Grooming can be performed by the veterinarian or an astute, skilled veterinary technician, however before the procedure begins one must always ask should the bird be groomed and should the bird be groomed at my practice?
The rabbit has a relatively short prothrombin time and whole blood quickly clots at room temperature. To minimize the risk of clot formation, it can be helpful to pre-heparinize the needle and syringe by drawing heparin into the needle and expelling the excess from the hub. The total volume of blood that can be safely collected typically ranges from 0.5% to 1.0% body weight. Collect smaller volumes from geriatric patients or those suspected to have anemia or hypoproteinemia.

Pet ferrets are easily handled using minimal restraint and a little petting. And with the exception of nursing females, ferrets rarely bite although young ferrets or “kits” may nip. Manual restraint is required for these lively, active creatures during uncomfortable procedures like obtaining a rectal temperature or during procedures that call for the animal to remain still like abdominal palpation. Use this video clip or text with still images to review handling techniques such as scruffing and stretching.
