Thank you for your constant support and for always making me laugh. Samantha Taylor To my partner, Richard, for constantly inspiring me to be a better clinician, and to my many animals and patients who continue to teach me so much. Andrea Harvey xi This page intentionally left blank Preface Samantha Taylor and Andrea Harvey are both experienced clinicians and internation- ally recognized Specialists in Feline Medicine and have treated a large variety of feline medicine cases both in the United Kingdom and Australia. Having worked together for some years, their writing a book which collects together examples of some of the types of cases they have seen, from the more common to the unusual, was a challeng- ing but rewarding task. During their specialist training the editors have consulted many texts during revi- sion and when tackling challenging cases. They wanted to write a new type of textbook that was highly practical, user friendly and provides the reader with access to useful information at the turn of a page. Their aim has been to provide veterinary students and practitioners with real, and as such not always straightforward, cases covering a wide variety of disciplines, giving readers of Feline Medicine: Test and Review a useful resource with which to test their knowledge and learn a bit more about cats. The editors hope they have achieved their aim and that readers of this book feel better able to handle the challenges that this complex and interesting species presents to them in their clinics. xiii This page intentionally left blank Abbreviations ACE Angiotensin converting enzyme ACEi Angiotensin-converting enzyme inhibitor AChRAb Acetylcholine receptor antibody ACP Acepromazine ACT Activated clotting time ACTH Adrenocorticotrophic hormone ADH Alcohol dehydrogenase AFB Acid-fast bacilli AGP Acid glycoprotein AKI Acute kidney injury ALP Alkaline phosphatase ALT Alanine transaminase Ao Aorta APTT Activated partial thromboplastin time ARB Angiotensin

  • A Vaccination Appointment
    What To Expect: A Vaccination Appointment This page is designed to give you a head's up on what you can expect when you take your pet in for his or her vaccination appointment. The page also discusses what you should expect from your veterinarian during a vaccination appointment. If you have any questions, please call your Shuswap veterinary care team at 250-832-6069. Here’s a basic rationale People and animals use antibodies to fight many viral and bacterial diseases. Your puppy or kitten will have received its first dose of disease fighting antibodies in the first 24 hours of its life, through the consumption of colostrum (first milk) from its mom, provided she was properly immunized. But these antibodies will diminish within a few short weeks. After that period of time it is up to the immune system to make those antibodies in sufficient numbers and thus create immunity. Vaccinations are given to stimulate the immune system to do exactly that. Some diseases require more immune stimulation than others to cause immunity and this is the reason why, for example, the first Rabies vaccine is good for a whole year, whereas the first Parvo or Distemper virus vaccination is only good for about 4 weeks. Currently, the general recommendation is to administer a series of three puppy at 8, 12 and 16 weeks of age with periodic booster vaccinations thereafter and for kitten vaccinations, two vaccinations at 8 and 12 weeks. Your veterinarian will help you work out an appropriate schedule specifically for your pet, as well as what diseases to vaccinate against.

  • Feline Asthma
    Avacta Animal Health Update: Feline Asthma Feline asthma is a common inflammatory disease of the lower airway affecting approximately 1-5% of the cat population and is believed to be triggered by aeroallergens1,2. The median age of presentation is at 4-5 years of age although, it is thought many cats presenting at this time will already have a long-term history of the disease, so the actual age of onset could well be significantly younger2. Clinical signs are variable and are sometimes categorised as acute, where episodic severe respiratory distress on expiration is seen, or as chronic, where more persistent wheezing and coughing of various degrees of severity may be observed1. However, approximately 10-15% of cases will present with a history of vomiting or paroxysmal hacking and coughing. This may result in a diagnostic work-up for gastrointestinal conditions such as hairballs, rather than one for respiratory issues2. Some cats with a history suggestive of asthma may be asymptomatic at the time of presentation. In these patients gentle tracheal palpation will often easily elicit a cough2. The subtly of clinical signs in some cats with chronic disease means the condition can remain undiagnosed for a significant period of time. This delay allows progression of pathological changes within the lung tissue2. Even with a thorough diagnostic respiratory investigation, discriminating feline asthma from other lower airway disorders (including chronic bronchitis and parasitic, infectious, cardiac or neoplastic conditions) is difficult which is, at least in part, why there are relatively few clinical trials into therapeutics for the disease1-3. Diagnosis is usually through a combination of history, clinical signs, thoracic radiography, exclusion of respiratory parasites, bronchoalveolar lavage cytology and response to trial therapy with bronchodilators and glucocorticoids1.

  • The Yellow Cat: Diagnostic & Therapeutic Strategies
    Peer Reviewed THE YELLOW CAT: DIAGNOSTIC & THERAPEUTIC STRATEGIES The Yellow Cat: Diagnostic & Therapeutic Strategies Craig B. Webb, PhD, DVM, Diplomate ACVIM (Small Animal Internal Medicine) Colorado State University There is no mystery when it comes to a “yellow” cat. Icterus and jaundice—both of which describe a yellowish pigmentation of the skin—indicate hyperbilirubinemia, a 5- to 10-fold elevation in serum bilirubin concentration. However, this is where the certainty ends and the diagnostic challenge begins. The icteric cat presentation is not a sensitive or specific marker of disease, despite the visually obvious and impressive clinical sign (Figure 1).1 The objective of this article is to briefly review differentials for hyperbilirubinemia in the cat, and present a diagnostic and therapeutic strategy that will help practitioners approach this problem in an efficient and effective manner.

  • Feline Obesity: Food Toys and Owner-Perceived Quality of Life During a Prescribed Weight Loss Plan
    Feline Obesity: Food Toys and Owner-Perceived Quality of Life During a Prescribed Weight Loss Plan Lauren Elizabeth Dodd Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science In Biomedical Veterinary Sciences Megan Shepherd, Chair Sherrie Clark Nick Dervisis Kathy Hosig May 16, 2019 Blacksburg, VA Keywords: Feline, Obesity, Weight loss Copyright © Lauren Dodd Use or inclusion of any portion of this document in another work intended for commercial use will require permission from the copyright owner. ACADEMIC ABSTRACT The prevalence of overweight and obesity in the feline population is estimated to be 25.7% and 33.8%, respectively. Feline obesity is associated with comorbidities such as insulin resistance and hepatic lipidosis. Several risk factors are associated with obesity including middle age, neuter status, decreased activity, and diet. Obesity management is multifaceted and includes client education, diet modification, and consistent monitoring. Successful obesity management may be dependent on owner perception of their cat’s quality of life during a prescribed weight loss plan. Low perceived quality of life may result in failure to complete the weight loss process. Food toys may be used to enhance environmental enrichment, allow cats to express their natural predatory behavior and overall improve owner-perceived quality of life. Therefore, we set out to investigate the role of food toys in owner-perceived quality of life of obese cats during a prescribed weight loss plan. Fifty-five cats with a BCS > 7 were enrolled in a double-blinded weight loss study and randomized into one of two groups: food toy (n=26) or food bowl (n=29).

Gaithersburg,MD Nishi Dhupa, BVM, MRCVS, DACVECC, DACVIM Cornell University ABSTRACT: Treatment of feline bronchial asthma is directed toward promoting bron- chodilation, reducing inflammation, and restoring normal mucus clearance. Therefore, determining and subsequently eliminating the inciting cause(s) of feline bronchial asthma should be the therapeutic priority of veterinary practitioners. Emergency treatment, including supplemental oxygen ther- apy, glucocorticoids, β2-adrenergic agonists, and methylxanthines, is often indicated. Long-term therapy is aimed at further reducing inflam- matory cell infiltration into the tracheobronchial tree and may be accom- plished with inhalant glucocorticoids and antileukotriene medications. eline bronchial asthma is a reversible respiratory condition of the lower airways char- acterized by altered airway immunosensitivity. Many medications, including β2- Fadrenergic agonists and glucocorticoids, are available for treating acute and chronic feline bronchial asthma (see boxes on page 427; Table 1).

  • Standard and Out-There Treatments for Feline Asthma Leah A. Cohn
    Standard and Out-There Treatments for Feline Asthma Leah A. Cohn, DVM, PhD, DACVIM (SAIM) Professor, Department Veterinary Medicine and Surgery, College of Veterinary Medicine, University of Missouri, MO, USA INTRODUCTION Feline asthma is one of the most common bronchopulmonary diseases in cats and is responsible for substantial morbidity and occasional mortality. It is an IgE mediated hypersensitivity response against what otherwise would be harmless environmental aeroallergens. Exposure to an allergen allows for production of allergen-specific IgE formation. Those IgE antibodies then bind to mast cells on respiratory mucosal surfaces. Upon re-exposure to allergen, IgE on the surface of the mast cell bind allergen and send an intracellular signal to trigger mast cell degranulation. Mediators that are either immediately released from granules or later synthesized within mast cells are major contributors to signs of asthma. Inflammation in the airways leads to cellular infiltration (mostly eosinophils), increased mucus production, bronchoconstriction, and creates permanent architectural changes in the lung called airway remodeling. All of these lead to clinical signs of asthma. CLINICAL PRESENTATION OF THE ASTHMATIC CAT Any cat may have asthma, although it is most commonly diagnosed in young to middle aged cats and may be more common and/or severe in Siamese cats. Typical clinical signs include some combination of coughing, wheeze, and intermittent respiratory effort or distress. Signs are often slowly progressive but can cause severe bronchoconstriction and sudden dyspnea. Differential diagnosis for respiratory distress includes congestive heart failure or pleural effusion, while differential diagnosis for cough includes pulmonary parasites and infectious or non-infectious bronchitis. Although routine blood, urine, and fecal tests help evaluate overall health and rule out other disease, radiography and airway lavage are the most useful tests.

  • Understanding Feline Asthma What Is Feline Asthma? Feline Asthma Is a Common Cause of Lower Airway Disease with Signs Beginning in Young to Middle Age Cats
    Understanding Feline Asthma What is feline asthma? Feline asthma is a common cause of lower airway disease with signs beginning in young to middle age cats. The disease is triggered by breathing in environmental particles that trigger an allergic reaction. Once these allergens are inhaled, they are recognized by the immune system and inflammation begins. Inflammatory cells are recruited to the airway and produce chemicals that make the inflammation even worse. This vicious cycle leads to more and more inflammation. With more inflammation comes more disease. This excessive inflammatory response leads to narrowing of the airway, allergic airway inflammation, and eventually to structural changes to the airways themselves, all of which are hallmark findings in patients with asthma. What do cats with asthma look like? The most likely symptom that you will notice if your cat develops asthma is a cough. It may also have an increased breathing rate or difficulty breathing. The severity of signs is highly variable between pets, and variable over time. Some cats may even require immediate medical attention for a sudden onset of open mouth breathing, increased breathing rate, or increased breathing effort. Most commonly, your cat may have an intermittent cough but appear normal between episodes. Coughing can be difficult to notice in cats and is often mistaken for hacking up hair- balls. Your veterinarian may notice that your cat has an increased breathing rate and wheezes when it exhales. The inconsistency in signs makes diagnosis of asthma nearly impossible without taking into account your cat’s history, along with examination and diagnostic test findings.
