Presenting problem: Aural Abscess in Turtles
The turtle ear is a simple structure that sits caudoventral to the eye covered by a large scale called the tympanic scute. As in many reptiles, the external ear is absent in chelonians. The tympanic membrane sits flush against the skin just underneath the tympanic scute. There is one ossicle, the columella, which crosses the large tympanic cavity to insert medially on the oval window of the cochlea. A narrow Eustachian tube connects the middle ear to the oropharynx.
Aural abscesses are well-encapsulated, caseous plugs that slowly develop until it fills the tympanic cavity. The cause of aural abscessation is not completely understood…

Presenting problem: Stomatitis in Reptiles
Stomatitis, also known as “mouth rot”, ulcerative stomatitis, necrotic stomatitis, and/or periodontal disease is a common problem in snakes and lizards. Stomatitis is less common in chelonians and crocodilians, and often presents as a stomatitis-rhinitis complex in tortoises. This presenting problem article explores the pertinent anatomy involved, key points of urgent care, as well as tips for case management.
Procedure Equipment Checklists
Do you have everything? Shared by registered veterinary technician and veterinary technician specialist, Jill Murray of Oklahoma State University, review our collection of procedure equipment checklists. Checklists are used in clinical practice to make preparation for procedures more efficient and more consistent, thereby improving the quality of care. Use these equipment checklists to train students and staff, or simply to jog your memory for procedures performed only sporadically.
Presenting problem: Anticoagulant Rodenticide Toxicosis in Free-Living Birds of Prey
Why is this bird bleeding? Anticoagulant rodenticide exposure in birds of prey has been documented in the United States, Canada, and Europe. Anticoagulant rodenticides have been commonly used over the past decades for control of rodent populations and these rodenticides can cause toxicosis in birds of prey via consumption of poisoned prey.
Anticoagulant rodenticides are divided into two categories: first generation rodenticides like warfarin and second generation rodenticides, such as brodifacoum. Second generation anticoagulant rodenticides are more toxic and also have…
Laboratory Assessment of the Bleeding Exotic Animal Patient
Hemorrhage in the critical patient can occur from a number of reasons. Before a blood sample is collected, carefully weigh the risk to the exotic animal patient against the clinical value of the test results. What will you do with this information? How will it affect your clinical plan? EDTA is the most commonly used anticoagulant in small mammals; lithium heparin is commonly used in birds and reptiles. Whenever possible, make a blood film immediately after venipuncture using fresh blood free of anticoagulant. Most adult small mammal hematocrits range from…
Presenting problem: Crop Burn in Birds
Crop burns are commonly caused by thermal injury in young birds and, in rare instances, by ingestion of caustic chemicals in adult birds. Crop burn is generally caused by feeding formula that is too hot (>110ºF or 43.3ºC) or less commonly, contact with a heat lamp or heating pad. Damage typically occurs in the gravity dependent right ventral region of the crop where the weight of the food bolus presses heated material against the skin. This increased thermal exposure can lead to necrosis of the crop wall and skin forming a fistula that can leak food.
Blood Collection in Ferrets
All but the weakest ferrets can be challenging to restrain for blood collection. Consider sedation or general anesthesia, particularly if the handler or phlebotomist is relatively inexperienced; however remember that anesthesia can affect ferret hematology.

Veterinary Answers Case Study: 5-Year-Old Cockatoo With Open-Mouth Breathing and Poor Grip
This case study is based on a report prepared by Veterinary Answers Consultant, Gwen Flinchum, DVM, Dipl. ABVP (Avian). A 5-year old female umbrella cockatoo is presented for lethargy, open-mouthed breathing, and difficulty gripping of 2-3 days duration.
Oral Examination in Rabbits and Rodents
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.
Backyard Poultry Primer
Backyard or hobby flocks consist of meat and game birds; or ornamental or show birds. This review article, co-authored by poultry veterinarian, Teresa Morishita, offers tips on the basic clinical approach to backyard poultry as well as differential diagnosis lists for common clinical problems. Conditions commonly encountered in backyard chickens and turkeys often include endoparasites, like Eimeria spp., pasteurellosis or fowl cholera, mycoplasmosis, staphylococcosis, and colibacillosis. Diseases important for public health concerns, such as avian influenza and Newcastle disease, are also discussed.
Basic Cytology of the Avian Gastrointestinal Tract
Historically, routine Gram’s stains were performed in apparently healthy birds. As our understanding of avian medicine has grown, avian veterinarians have questioned the reliability and validity of Gram’s stain cytology as a screening test. Cytology is indicated when specific problems are reported during a detailed medical history or when…
Presenting problem: Trauma in Ferrets
Ferrets are small, flexible, mischievous, and curious. This combination means that traumatic injury is a common problem, particularly when owners do not supervise their pets or “ferret proof” their living quarters. For instance, reclining chairs have been implicated in the injury and even death of many ferrets. Ferrets may also be accidentally stepped on or become trapped within a confined space. Trauma can result in a constellation of injuries that may affect the head, thorax, abdomen, spine, and limbs.
Blood Collection in Rabbits
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.

Mammary Tumors in Small Mammals
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.
Thoracocentesis in Ferrets
Exotic animal care is frequently a balancing act between concepts true for all medicine and species-specific information. Management of pleural effusion in the ferret relies on the same tests and treatments used in dogs and cats, including chest taps when indicated.
Presenting problem: Cloacal Prolapse in Birds
Cloacal prolapse is a serious and potentially life-threatening problem. Prolapses can originate from the cloaca, oviduct or intestinal tract. The cloaca normally prolapses during egg laying or oviposition, and normal retraction of the cloaca may be slowed or absent in an obese hen or one with hypocalcemia. Excessive abdominal contractions caused by an abnormal egg, dystocia, cloacal disease, gastrointestinal disease or chronic mastubatory behavior can also promote prolapse.
Otitis in Rabbits
The pathogenesis of otitis is often multifactorial in the rabbit. Predisposing factors such as ear conformation increase the risk of otitis in certain breeds. All rabbits have a relatively narrow ear canal, however in Lop-eared rabbits the fold in the ear cartilage is such that the lumen is entirely closed off preventing normal drainage of cerumen from the ear.
Venipuncture in Small Mammals
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.
Omega-3 Fatty Acids and Atherosclerosis in Birds
What is atherosclerosis?
Atherosclerosis is characterized by fibrous plaques between the tunica intima and the internal elastic lamina of the vasculature. The heart, great vessels, and peripheral vessels of all sizes can be affected. Atherosclerosis begins with the formation of fatty streaks, which can eventually progress into fibrous plaques and complicated lesions…
Mange in Exotic Small Mammals
Most species of mites are host-specific, however take special precautions, such as wearing exam gloves, to minimize the spread of potentially zoonotic pathogens. Humans that become infested with Sarcoptes scabei may develop wheals, vesicles, papules, and intense pruritus. Pet owners, especially children, may become infected with…
Clinical Pathology for Exotic Small Mammals
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.
Basic Information Sheet: African Pygmy Hedgehog
The African pygmy hedgehog is a native of West and Central Africa. When threatened, the hedgehog curls into a ball, extends its spines, puffs up, and hisses. When exposed to a new object, hedgehogs may exhibit “self anointing” or “anting”. The new object is licked until thick, frothy saliva collects and is then…
Dental Disease in Rabbits and Rodents
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.
Cardiac Disease in Ferrets
Cardiac disease is common in middle-aged and older domestic ferrets. Dilated cardiomyopathy is the most common heart disorder in older ferrets, however hypertrophic cardiomyopathy and valve conditions also occur in the ferret. Clinical signs range from asymptomatic disease to fulminate heart failure with problems such as anorexia, weakness, and dyspnea.
Encephalitozoonosis in Pet Rabbits
Neurologic diseases are relatively common in companion rabbits, and recognition of these conditions by the exotic animal clinician is very important. Encephalitozoonosis is endemic in the pet rabbit population worldwide, and is an important cause of neurologic disease in this species.
Respiratory Disease in Rats
One of the more common illnesses in rats is respiratory disease. Although most cases of respiratory disease in the rat are multifactorial, the most significant and serious bacterial pathogen is Mycoplasma pulmonis…
Fungal Disease in Avian Patients
Fungi are among the most common causes of infectious disease in captive birds, and fungal diseases can be challenging to diagnose, as well as treat. Because fungi are typically opportunistic, causing non-contagious disease in susceptible individuals, prevention and treatment require an understanding of etiology as well as predisposing factors.
Burns in the Avian Patient
Burns are common in avian medicine. Many burns result from contact with hot liquids such as scalding water or cooking oil. Electrical burns arise from chewing on electrical wires and burns may also occur when pre-weaning birds are fed hot formula. Burns resulting from entrapment in burning buildings or inside containers, such as chick incubators with burning bedding, are not as common but are much more difficult to treat due to the complication of smoke inhalation.
Diagnosing and Treating Avian Neurologic Disease
The cranial nerve exam differs little from that of mammals, however there are differences in innervation. As in mammals, menace and pupillary light response (PLR) require use of cranial nerves II (optic) and III (oculomotor), however menace is difficult to interpret in birds. Also, PLR may be overridden in birds due to the presence of striated iridal muscle. Evaluate PLR early in the exam using a sudden, bright light directed toward the medial canthus. Consensual PLR is absent due to…
Measuring Avian Blood Pressure
Arterial blood pressure measurement is an important tool in the management of the critically ill bird. Systolic blood pressure is the pressure exerted against the blood vessel wall during contraction of the heart. Although direct arterial pressure measurement is ideal, it is not commonly used because of the need for specific technical skill, invasive nature of the procedure, and cost of equipment.
Avian Respiratory Emergencies: An Approach to the Dyspneic Bird
After recognizing a dyspneic bird, the clinician’s initial response should be: Hands Off!! Dyspneic birds can die soon after presentation with the additional stress of restraint and handling. Therefore minimize handling and place the bird in an oxygen-rich cage. Humidify air and provide 40 to 50% oxygen. As in mammals, oxygen therapy is potentially toxic if given for prolonged periods at high levels.
