  • And Feline Infectious Peritonitis (FIP)
    Feline Coronavirus (FCoV) and Feline Infectious Peritonitis (FIP) VETERINARY GUIDE 10 What is Feline Coronavirus or FCoV? FCoV is a common and contagious virus which is passed in the faeces of cats. It is more commonly found in multi-cat households and does not affect other animals or people. How does a cat catch FCoV? FCoV is caught by inadvertently swallowing the virus, through contact with other cats, litter trays or soil where other cats have toileted. Exposure to faeces in the litter tray is the most common means of transmission. Forty per cent or more of cats will be infected with the virus at some time in their lives and most owners will be unaware of it. Nearly every cat that encounters the virus will become infected and most will remain healthy and the majority will clear the virus themselves. What problems does FCoV cause? Most cats do not display any sign of being infected with FCoV, although some cats get diarrhoea for a few days. These cats tend to shed the virus in their faeces for a few months and remain healthy. In a very small percentage of cats, the virus mutates and causes a fatal disease called feline infectious peritonitis (FIP). This is more likely to occur in multi-cat environments and can take weeks, months or occasionally years after the initial infection with FCoV to develop. If a cat clears FCoV and doesn’t develop FIP, is it then immune? Unfortunately not, a cat can become re-infected with FCoV again at any time and can be susceptible to it mutating and causing FIP.

  • Antibiotic Use Guidelines for Companion Animal Practice (2Nd Edition) Iii
    ii Antibiotic Use Guidelines for Companion Animal Practice (2nd edition) iii Antibiotic Use Guidelines for Companion Animal Practice, 2nd edition Publisher: Companion Animal Group, Danish Veterinary Association, Peter Bangs Vej 30, 2000 Frederiksberg Authors of the guidelines: Lisbeth Rem Jessen (University of Copenhagen) Peter Damborg (University of Copenhagen) Anette Spohr (Evidensia Faxe Animal Hospital) Sandra Goericke-Pesch (University of Veterinary Medicine, Hannover) Rebecca Langhorn (University of Copenhagen) Geoffrey Houser (University of Copenhagen) Jakob Willesen (University of Copenhagen) Mette Schjærff (University of Copenhagen) Thomas Eriksen (University of Copenhagen) Tina Møller Sørensen (University of Copenhagen) Vibeke Frøkjær Jensen (DTU-VET) Flemming Obling (Greve) Luca Guardabassi (University of Copenhagen) Reproduction of extracts from these guidelines is only permitted in accordance with the agreement between the Ministry of Education and Copy-Dan. Danish copyright law restricts all other use without written permission of the publisher. Exception is granted for short excerpts for review purposes. iv Foreword The first edition of the Antibiotic Use Guidelines for Companion Animal Practice was published in autumn of 2012. The aim of the guidelines was to prevent increased antibiotic resistance. A questionnaire circulated to Danish veterinarians in 2015 (Jessen et al., DVT 10, 2016) indicated that the guidelines were well received, and particularly that active users had followed the recommendations. Despite a positive reception and the results of this survey, the actual quantity of antibiotics used is probably a better indicator of the effect of the first guidelines. Chapter two of these updated guidelines therefore details the pattern of developments in antibiotic use, as reported in DANMAP 2016 (www.danmap.org).

  • Dog and Cat Vision
    A professional publication for the clients of East Valley Animal Clinic WINTER 2018 East Valley Animal Clinic 5049 Upper 141st Street West Apple Valley, Minnesota 55124 Dog and Cat Vision Phone: 952-423-6800 Kathy Ranzinger, DVM Have you ever wondered about the difference between human vision and what Pam Takeuchi, DVM your dog or cat sees? There are a number of differences, and they don’t necessarily Katie Dudley, DVM see better than us, just differently. Mary Jo Wagner, DVM Have you ever noticed how a dog or cat’s eyes shine in the dark? This is because of Greg Wilkes, DVM a structure called the tapetum. It is a thin layer on the retina that reflects up to 130 www.EastValleyAnimalClinic.com times more light than what humans see. This structure, along with the large round shape of the dog and cat eye and the vertical shape of the pupil, allow a maximum Find us on Facebook! amount of light into the eye, allowing your cat to easily navigate the house in the middle of the night. Dogs and cats have less color vision than humans. Color vision is determined by the number of cones, which are color receptors, on the retina. Dogs possess about 20% of the color receptors that humans do. Dogs and cats outperform us in detection of shades of grey, which helps with night vision. Dogs’ color vision is similar to humans’ that have red-green color blindness: they see color, but do not have the broad spectrum of color vision that we see.

  • Understanding Human Factors Involved in the Unwanted Cat Problem
    UNDERSTANDING HUMAN FACTORS INVOLVED IN THE UNWANTED CAT PROBLEM Sarah Jane Maria Zito BVetMed MANZCVS (feline medicine) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 School of Veterinary Science I Abstract The large number of unwanted cats in many modern communities results in a complex, worldwide problem causing many societal issues. These include ethical concerns about the euthanasia of many healthy animals, moral stress for the people involved, financial costs to organisations that manage unwanted cats, environmental costs, wildlife predation, potential for disease spread, community nuisance, and welfare concerns for cats. Humans contribute to the creation and maintenance of unwanted cat populations and also to solutions to alleviate the problem. The work in this thesis explored human factors contributing to the unwanted cat problem—including cat ownership perception, cat caretaking, cat semi-ownership and cat surrender—and human factors associated with cat adoption choices and outcomes. To investigate human factors contributing to the unwanted cat problem, data were collected from 141 people surrendering cats to four animal shelters. The aim was to better understand the people and human-cat relationships involved, and ultimately to inform strategies to reduce shelter intake. Participants were recruited for this study when they surrendered a cat to a shelter and information was obtained on their demographics, cat interaction history, cat caretaking, and surrender reasons. This information was used to describe and compare the people, cats, and human-cat relationships contributing to shelter intake, using logistic regression models and biplot visualisation techniques. A model of cat ownership perception in people that surrender cats to shelters was proposed.

  • Vaccinations in Cats
    Vaccinations in Cats 803-808-7387 www.gracepets.com Recent advances in veterinary medical science have resulted in an increase in the number and type of vaccines that are available for use in cats, and improvements are continuously being made in their safety and efficacy. Some vaccines are more or less routinely advocated for all cats (‘core’ vaccines) whereas others are used more selectively according to circumstances. However, in all cases the selection of the correct vaccination program for each individual cat, including the frequency of repeat, or booster, vaccinations, requires professional advice. Currently cats can be vaccinated against several different diseases: “Core” Vaccines, as recommended by the American Association of Feline Practitioners (AAFP) for all kittens and cats: 1. Feline panleukopenia, FPV or FPL (also called feline infectious enteritis) caused by FPL virus or feline parvovirus 2. Feline viral rhinotracheitis, FVR caused by FVR virus, also known as herpes virus type 1, FHV-1 3. Feline caliciviral disease caused by various strains of Feline caliciviruses, FCV 4. Rabies caused by Rabies virus “Non-core” or discretionary vaccines, recommended for kittens and cats with realistic risk of exposure to specific diseases: 1. Feline chlamydial infection 2. Feline leukemia disease complex caused by Feline leukemia virus, FeLV 3. Feline Infectious Peritonitis (FIP) caused by FIP virus or Feline Coronavirus 4. Giardiasis caused by the protozoal parasite Giardia 5. Bordetellosis caused by the bacterium Bordetella bronchiseptica 6. Ringworm 7. Feline Immunodeficiency Virus (FIV) How do vaccines work? Vaccines work by stimulating the body's defense mechanisms or immune system to produce antibodies to a particular microorganism or microorganisms such as a virus, bacteria, or other infectious organism.

FHT is due to the autonomous oversecretion of thyroid hormones (T4 and T3), resulting in an increased metabolic rate. c. 98% of cases of FHT result from benign adenomatous hyperplasia of the thyroid glands; 2% results from thyroid carcinoma. d. Clinical signs in well-established cases include weight loss, polyphagia, increased activity, and polydipsia/polyuria. e. A common scenario in practice is to suspect FHT based on weight loss since the last wellness examination, the palpation of one or both enlarged thyroid lobe(s), and the detection of a new cardiac murmur and resting tachycardia.

Beatty 1,* and Katrin Hartmann 2 1 Department of Veterinary Clinical Sciences and Centre for Companion Animal Health, Jockey Club College of Veterinary Medicine and Life Sciences, City University, Hong Kong, China 2 Medizinische Kleintierklinik, Centre for Clinical Veterinary Medicine, LMU Munich, 80539 Munich, Germany; [email protected] * Correspondence: [email protected] 1. Introduction Viral diseases play a very important role in feline medicine, and research on feline viruses and viral diseases is a well-established field that helps to safeguard the health of domestic cats and non-domestic felids, many of which are endangered. This research also informs an expanding multibillion-dollar companion animal veterinary industry and, both directly and indirectly, contributes to the health of humans and the other animals that interact with cats. Last but not least, feline virus infections serve as important animal models for human viral diseases, such as immunodeficiency or coronavirus infections. This Special Issue brings together 27 papers, including four reviews, covering diverse aspects of feline viruses and viral diseases. The recent emergence of the COVID-19 pan- demic, caused by a highly pathogenic coronavirus of animal origin, SARS-CoV-2, further emphasizes the relevance of companion animal virology to global One Health. 1.1.
