Even the most steadfast and seasoned veterinary anesthetist can find themselves intimidated by exotic animal patients. Standard veterinary anesthesia monitors are not designed to read the extremely high (or extremely low) heart rates and respiratory rates of some exotic animal patients. Despite these challenges, valuable information can be gathered from monitoring tools as well as hands-on techniques. Essential vital signs, such as heart rate and rhythm, respiratory rate and depth, body temperature, and mucous membrane color should all be evaluated.
Insufficient dietary fiber can turn a happy, healthy rabbit into a HUGE, potentially catastrophic, clinical problem. Read about the basis for a healthy diet in Hay: Feeding Small Herbivores, reviewed by forage extension specialist, S. Ray Smith.
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.
Can’t quite recall the dental formula of the African pygmy hedgehog–or perhaps you never knew? Use LafeberVet’s “Small Mammal Dental Formulas: Cheat Sheet” as a quick and easy clinical resource.
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.
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.
Veterinary nurses and veterinary technicians take the post-test. With a passing grade of 70% or higher, you will receive a continuing education certificate for 1 hour of continuing education credit in jurisdictions that recognize AAVSB R.A.C.E. approval.
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…
A wide range of dental abnormalities may be seen in rabbits, guinea pigs and chinchillas including incisor and cheek teeth malocclusion. Evaluation of the oral cavity is considered an essential part of the complete physical examination in small exotic companion mammals, both symptomatic and clinically normal individuals alike. Use this video clip or article with still images to review equipment needed as well chemical and manual restraint techniques for extraoral and intraoral exams.
An important differential for lumps and bumps: Mammary gland tumors are relatively common in rats and mice, and are also seen in African pygmy hedgehogs and guinea pigs. Get the facts about mammary tumors in small mammals. Review diagnostics, management, prognosis and prevention of this important condition.
Dental problems in rabbits and rodents are often related to either trauma or lack of normal wear and tooth elongation. When herbivores like rabbits, guinea pigs, and chinchillas receive concentrates, in the form of grain or pellets, with only limited access to hay and natural vegetation this diet provides too little tooth wear to compensate for the natural growth of the teeth.
More hay please…Prolonged chewing of tough, abrasive foods such as hay causes rapid tooth wear in rabbits and herbivorous rodents. To compensate for this, these species have permanent teeth that grow and erupt continuously, never producing anatomical roots.
