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.
Although the principles of emergency medicine critical care are universal for all species, this approach must be balanced with an understanding of the unique aspects of small mammal medicine. Use this summary page to review the basic approach to the exotic companion mammal patient and select additional links to supplement your knowledge base.
A variety of agents may be used in small mammals with ectoparasites. Download this easy-to-use table for a list of agents used to manage lice, flea infestation, mange or acariasis.
Released for National Veterinary Technician Week 2014, Nursing Care for Exotic Companion Mammals is part of an Exotic ICU series providing advice on the management of small exotic companion mammals in a critical care setting. Specific recommendations on caging, medicating, feeding, and monitoring the critical small mammal are explored as well as important potential sequelae to the stress of hospitalization.
Urolithiasis is characterized by single or multiple calculi throughout the urinary tract or by the presence of sandy material within the bladder and urethra. Uroliths are fortunately more of a historical disease in the ferret, while calculi are still an important problem in rabbits and rodents.
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.
Although some diseases are merely arranged alphabetically, other lists are based on the mnemonic acronym DAMNIT. This commonly used veterinary medical record scheme divides disease mechanisms into the following categories: degenerative, anomalous, metabolic, neoplastic or nutritional; infectious, inflammatory, idiopathic, immune-mediated, or infarct/vascular; and traumatic or toxic.
Providing nutrition to the hospitalized small mammal is a fairly straightforward process. Encourage owners to bring their pet’s “regular” diet to minimize the risk of food refusal or gastrointestinal upset. Also consider keeping the following food items available…
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.
Although fungal disease is uncommon in small mammals, dermatophytosis is the most common mycosis seen in clinical practice. Despite the low incidence of clinical disease, rodents are common asymptomatic carriers of dermatophytes. Fungal pathogens are generally more important for their zoonotic potential. Rodents are frequently asymptomatic carriers of ringworm, and transmission of disease to human caretakers is not uncommon.
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.
New to chinchillas or has it just been awhile since you’ve seen this species? Review LafeberVet’s list of the Top 10 things you should know before entering the examination room.
Conjunctivitis is a common clinical problem in chinchillas. Ocular irritation can arise from excessive dust bathing, inadequate cage ventilation and/or…
Heatstroke is the most severe form of heat-related illnesses. In this life-threatening condition, the body is unable to dissipate heat load at a rate that accommodates excessive heat levels.
Begin treatment immediately once heatstroke is suspected. Intensive care is aimed at reducing body temperature while supporting organ function. A variety of techniques can be used to lower core body temperature. Administration of intravenous or intraosseous fluids is a popular internal cooling technique that also serves to support organ function…
The chinchilla is a small mammal native to South America. Originally found in the Andes Mountains of Peru, Bolivia, Chile, and Argentina, chinchillas were hunted and trapped for their pelts to near extinction in the early 1900s. Chinchillas are now endangered in the wild and are only found in the mountains of northern Chile.
The natural diet of the chinchilla consists of grasses, cactus fruit, leaves, and the bark of small shrubs and bushes. The captive diet consists of…
Why syringe fed? A cornerstone of treatment is delivery of food containing high dietary fiber. Proper syringe-feeding technique is essential..
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.
Intravenous catheters are commonly placed in ferrets and rabbits to administer fluids and medications, induce anesthesia, and for delivery of analgesic drugs during and after surgery. Intravenous catheters are also placed with growing frequency in chinchillas, guinea pigs and other small exotic companion mammals. Use this video clip or text with still images to review patient selection, potential complications, equipment needed and step-by-step instructions for this technique, as well as daily fluid requirements, catheter maintenance, and patient monitoring.
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.
Mild to moderately ill exotic companion mammals are often syringe fed, and proper syringe-feeding technique is an essential skill for critical care nutrition of ferrets, rabbits, and rodents. Gastrointestinal stasis is one of the most common medical problems seen in small herbivores. A cornerstone of treatment is delivery of food containing high dietary fiber. Aggressive fluid therapy, often in the form of oral and subcutaneous fluids, is also crucial for successful management. Always address dehydration before beginning nutritional support. Get specific tips to improve your clinical success with this video clip or read the article with still images.
Chinchillas, like many small exotic mammals, are prey species that can become easily stressed in a hospital setting. Approach these patients calmly and quietly. Fortunately most pet chinchillas are relatively docile. They are typically used to being handled and will often come out of their cage voluntarily. Use this video and text with still images to review the cautions or potential complications of chinchilla restraint and handling well as the technique involved.
Hematological and serum chemistry tests are considered part of the minimum database, yet collecting blood samples from small mammals can be extremely challenging. This review article reviews the recommended venipuncture site in popular exotic companion mammals including many rodents, rabbits, ferrets, hedgehogs, and sugar gliders. Sample collection from peripheral vessels including the cephalic, saphenous, tail, jugular, ear, and submandibular vein is discussed.
Blind venipuncture sites such as the cranial vena cava and femoral vessels are also described. Veterinary health professionals are also acquainted with the potential risks associated with blood collection from these small species, especially those presenting in advanced diseased states. Tips for clinical success are also shared.
Although we’d like to believe you need look no further, exotic animal medicine is a diverse and varied topic. View LafeberVet’s ever-growing list of additional online resources on small mammal medicine.
Small mammals, such as rabbits and rodents, are stoic by nature and have evolved to mask their illness to avoid predation. This behavior can create a false sense of security in owners and a clinical challenge for veterinarians. In some cases, an animal that appears clinically normal may in fact have a terminal illness. Use hematology and biochemistry analysis to characterize the true physiological status of these species and aid in disease diagnosis.
Physical examination in exotic small mammals is performed similarly to examinations in dogs and cats, however many small mammals can easily become stressed. Approach these patients calmly, gently, and quietly. Gather all items that may be needed during the physical exam beforehand since it is essential to keep time to a minimum. Ideally schedule examination of nocturnal species such as sugar gliders, rats, and mice during the evening hours. It can also be helpful to dim the lights while examining these species.
Rabbits and rodents may suffer from a wide range of dental problems. Although the vast majority of cases are related injury or to lack of wear and tooth elongation, dental caries, a bacterial plaque-associated disease, may also be seen.
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.
