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.
Although patient history is important in all species, improper diet and substandard housing are often major contributors to illness in non-traditional pets. This means that a detailed and accurate history is often one of the most critical diagnostic tools for the exotic animal patient. This review focuses on birds, reptiles, and small exotic companion mammals, beginning with the signalment and presenting complaint, before moving onto the environmental history, dietary history, and of course the medical history.
Signs of illness in birds are often quite subtle until disease is advanced. Fortunately, quite a bit of information can be gleaned from a detailed history and careful observation. View this brief slideshow for tips on the visual examination.

The avian respiratory system has several unique and fascinating adaptations for flight that are important to clinicians. This webinar overviews the anatomy and physiology of the avian respiratory tract. Clinical correlates are pointed out as the presenter goes through anatomy and physiology. Clinical signs of respiratory disease in birds are then discussed along with how the clinician can use these signs to anatomically locate the origin of the problem to the upper respiratory tract, the major airways, the pulmonary parenchyma, and/or the coelomic cavity.
This presenting problem article reviews the basic approach to the dyspneic ferret beginning with clinical signs of the dyspneic ferret, key points of urgent care, as well as case management. This latter section reviews tips on taking the history, performing the physical exam, important differential diagnoses, as well as the diagnostic/therapeutic approach.
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.
Part of LafeberVet’s Basic Rabbit Care Teaching Module, the Rabbit Anatomy Basics slideshow is a 22-minute recording designed to impart a basic understanding of rabbit anatomy for the veterinary technician and veterinary nurse. This slideshow may also be of use as a basic learning aid for veterinary medical students and as a basic refresher for the clinician.
The domestic or European rabbit, Oryctolagus cuniculus, is descended from wild rabbits of Europe and northwestern Africa, where free-ranging Oryctolagus are still found. Rabbits come in many different shapes, sizes, and colors. The American Rabbit Breeder Association currently recognizes 49 rabbit breeds, and the number listed by the British Rabbit Council is even higher. Many house rabbits have several different breeds in their background. View this 8-minute slideshow to review common rabbit breeds seen in clinical practice as well as their associated disease predispositions.
The “Pigeon Disease Primer” explores important differential diagnoses for common clinical problems observed in pigeons and doves. Although the clinical approach to the columbiform relies on the same concepts of “One Medicine” used in all species, many of the infectious diseases of pigeons are relatively unique to this taxonomic group, or at least much more prevalent when compared to psittacine birds or songbirds.
Pigeons and doves belong to order Columbiformes and family Columbidae. Within family Columbidae, there are five subfamilies consisting of 42 genera and 308 species. Pigeons and doves are found on every continent except Antarctica, and they live in virtually all types of terrestrial habitats. Columbids tend to be stocky birds with relatively small heads, short beaks, as well as a fleshy cere and a bare ring of skin around the eyes. Columbiforms also tend to have short, squat legs and long keels.
Although pigeons and doves are a diverse group of birds, they do share some clinically significant anatomy and physiology, including a large, bilobed crop or ingluvies, crop milk production, as well as a vascular plexus found in the subcutis of pigeons. 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.
The approach to a prey species like the rabbit often calls for a profound paradigm shift for clinicians used to dealing only with cats and dogs. Rabbits can stress very easily in a clinical setting and the challenge of managing a small mammal like the rabbit increases exponentially when they are presented for illness or injury.

Red leg syndrome, also known as “pink belly disease” or bacterial dermatosepticemia, is one of the most common clinical conditions of captive frogs. Associated with peracute to acute bacterial septicemia, red leg is generally a disease of captive animals although the condition has also been implicated in rare mass mortalities of wild amphibians. This presenting problem article reviews clinical findings in red leg syndrome, pathogenesis of disease, as well as key points of urgent care and prognosis. The basics of case management are then reviewed: differential diagnoses, diagnostics, treatment, prevention and control.
Gastric dilatation or “bloat” and gastrointestinal obstruction is an acute and life-threatening condition of pet rabbits commonly caused by an obstruction with pellets of compressed hair. The discussion portion of this Case Challenge reviews onset, clinical signs, and diagnostic test results of obstructive and non-obstructive gastrointestinal disease. This condition is considered a surgical emergency and key points of urgent care strive to stabilize the patient through analgesia, decompression when indicated, and supportive care. Surgery is discussed as well as recommendations for patients that cannot go to surgery due to clinical or financial constraints. Follow-up care as well as homecare recommendations, disease prevention, and prognosis are also explored.
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.

A simple retweet of a turtle eye examination at the National Aquarium inspired a day of terrapin-friendly tweets by LafeberVet. Twitter topics ranged from turtle and tortoise ophthalmic anatomy to chelonian clinical problems like blepharedema, commonly associated with hypovitaminosis A in aquatic turtles.
It is 10 p.m. in your veterinary emergency hospital and a dreaded call comes in. A panicked owner is in tears because their beloved pet is in crisis. In most cases, your team will quickly gather supplies and move swiftly to prepare for the emergent patient. This patient may strike fear in many veterinary professionals, however, because it is the dreaded avian patient presenting to a general veterinary practice.
Released for National Veterinary Technician Week 2014, Tips and Tricks for the Avian Patient is part of an Exotic ICU series that provides advice on the management of birds in a critical care setting.
Body condition scoring or BCS is a useful tool for assessment of a patient’s general health status and evaluation of a patient’s food supply. The BCS system described below is based on scores between 1 and 5, with 1 being emaciated and 5 being obese for the “generic” bird. Currently there is no universally agreed upon BCS system for the avian patient due to…
The site visit allows the veterinarian to appreciate intricate facility details. Unless there is an emergency, schedule visits during the non-breeding season and only visit one site daily to prevent potential iatrogenic contamination of facilities. I usually schedule appointments in the morning prior to going to the clinic. An aviary map or blue print of the aviary layout will help you visualize where birds are in relation to each other.
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…
Pediatrics is one of the most fascinating and rewarding fields of avian medicine. The key to hand raising healthy psittacine chicks is a strong preventive medicine program based on sound husbandry practices. Physical examination is an important part of preventive health care.
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.
Guinea pigs tend to be shy, sweet-natured creatures. Guinea pigs are prey species. Their survival depends on the ability to be alert and respond quickly, and they possess acute senses of smell and hearing. Approach guinea pigs in a calm, quiet manner…
Rabbits are prey species. Their survival depends on the ability to be alert and respond quickly, and they possess acute senses of smell and hearing. Approach rabbits in a calm, quiet manner. Stressed or critically ill rabbits may not tolerate prolonged handling. Evaluation and treatment may need to proceed slowly in stages.
Lethargy, total or partial anorexia, a reduction in fecal output, or scant fecal size can all indicate critical illness in rabbits. Problems that slow the gut are often uncomfortable, however rabbits tend to mask pain and discomfort, especially when frightened. Signs of fear and pain in the rabbit can include…
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…
Abnormal urine in the rabbit typically appears white and chalky or pigmented. These changes can be related to the unique metabolism of calcium in the rabbit. Rabbits absorb nearly all calcium ingested; therefore blood levels vary substantially with the calcium content of the diet…
In many birds, the eye is the most important sensory organ, and even partial impairment of vision has far-reaching consequences. Unfortunately, ocular lesions are a common finding during ophthalmic examination in birds of prey.
The large size of the raptor eye and its relative lack of orbital protection superiorly and laterally means any form of head trauma frequently involves the eye and its associated structures. In one report, ocular injuries were most commonly caused by vehicular collision, gunshot and leghold traps. The most common clinical finding in birds of prey presented for medical attention is hyphema. Trauma may also lead to…
Many exotic animals seen in clinical practice are prey species. In the wild, individuals that appear sick or injured are easy prey for predators, and they may even be segregated or attacked by group members. When faced with the stress of a strange examination room, most prey species will attempt to appear alert and strong as an instinctive survival adaptation.
Unfortunately the sedentary lifestyle of the companion bird makes obesity one of the most common forms of malnutrition seen in clinical practice. Pet birds are fed too much food or they are fed diets rich in sources of fat, such as sunflower seeds .
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.
Is your patient strong enough to handle manual restraint and a complete physical examination? In the debilitated or dyspneic patient, initially it may be prudent to place the patient in an incubator or oxygen cage in a dark, quiet room before evaluation. Even after the bird has had time to gather its strength and calm down after the stress of transport, it may only be strong enough to handle diagnostic testing, including physical examination, and treatment in stages.
Snake behavior will vary with the species, however the normal snake tends to be alert, responsive, and curious. Frequent tongue flicking is a sensory gathering behavior used to deliver scents to the vomeronasal organ. The normal snake is generally active, often coiling or twining its body. This is particularly true for smaller species. Signs of aggression in the snake may include…
Download LafeberVet’s Rabbit Dental Chart for use during clinical procedures ranging from standard dental examination to major orofacial surgery.
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.
If you see reptiles in your clinical practice, you will encounter diarrhea in tortoises, and less commonly turtles. This paper describes the basics of case management beginning with anamnesis, continuing with information on the examination, tests and potential treatments and concluding with client education.

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?
