Feline lower urinary tract disease

Introduction The term feline lower urinary tract disease (FLUTD) describes a collection of conditions that can affect the bladder and/or urethra of cats. Unfortunately, since the urinary tract can respond to insult in only a limited numbers of ways, the clinical signs are rarely indicative of a particular disease. While there are many conditions that can result in signs of FLUTD (see below) the vast majority of cases are idiopathic.

Feline diabetes mellitus in the UK: the prevalence within an insured cat population and a questionnaire-based putative risk factor analysis

Prevalence and risk factors for the development of diabetes mellitus (DM) in cats in the United Kingdom have not previously been reported. The prevalence of DM was evaluated in a large insured population and was found to be 1 in 230 cats. In this insured cat population Burmese cats were 3.7 times more likely to develop DM than non-pedigree cats. A convenience-sampling questionnaire-based study was used in order to identify putative risk factors for the development of DM. The univariate risk factor analysis identified being male, neutered, inactive, weighing ≥5 kg and having a history of corticosteroid treatment as significant risk factors for the development of DM in these cats. In addition, male cats treated with megestrol acetate had a significantly increased risk of developing DM compared to females. In contrast, there was no difference in DM occurrence between male and female Burmese cats. A multivariate classification tree-based model on the questionnaire data looking for interactions between risk factors, identified gender as the most important overall risk factor for the development of DM with low physical activity being the next most important risk factor for female cats and breed the next most important for male cats.

Feline tuberculosis: a literature review and discussion of 19 cases caused by an unusual mycobacterial variant

The literature relating to feline mycobacterial disease is reviewed and 19 cats with tuberculosis caused by a previously unknown strain of mycobacterium are discussed. The bacteria were found to have characteristics between those of Mycobacterium tuberculosis and M bovis. The paper considers the clinical signs, epidemiology and diagnosis of the cases, and discusses the possible origins of the organism, treatment regimens and zoonotic potential.

Prevalence of Tritrichomonas foetus infection in cats with diarrhoea in the UK

Faecal samples from 111 cats with diarrhoea that were living in the UK were submitted for the assessment of Tritrichomonas foetus infection by polymerase chain reaction (PCR). Sixteen (14.4%) samples were found to be positive. In agreement with studies from the USA, infected cats were predominantly of a year of age or less and of a pedigree breed, with Siamese and Bengal cats specifically over-represented in this population.

A pilot study using synthetic feline facial pheromone for the management of feline idiopathic cystitis

Synthetic feline facial pheromone (FFP) (Feliway; Ceva Animal Health) was assessed for the management of cats with recurrent feline idiopathic cystitis (FIC). Nine of 12 cats completed the randomised, double-blinded, placebo-controlled, crossover pilot study. They had their environment treated daily with either FFP or placebo for 2 months, after which time the treatment groups were reversed. Owners used visual analogue scales to define the severity of their cats clinical signs and behavioural changes. Five (56%) of the owners stated that their cats overall health was better when they were using FFP. Four (44%) of the owners noticed no difference between when using the FFP and when using the placebo. While there were no statistical differences between the two treatment groups there was a trend for the cats exposed to FFP to show fewer days with clinical signs of cystitis (FFP total, mean per cat±standard deviation, 30, 4.3±6.7; placebo 69, 9.9±19.1), a lower overall clinical score (1667, 238±476; 2009, 287±425), a reduced number of episodes of cystitis (9, 1.3±2.0; 10, 1.4±2.1) and reduced negative behavioural traits (e.g., less aggression and fear) (−128, −18.3±65.8; −73, −10.4±35.1).

Natural Borna disease virus infection in cats in the United Kingdom

Borna disease virus (BDV) is a novel PNA virus that has only recently been characterised and classified in a new virus family, Bornaviridae. The virus was detected in buffy coat cells from four of five cats with neurological disease and in the brains of five of 15 cats with nervous signs and of one of three cats with non-neurological disease. In a serosurvey of 111 cats the incidence of antibody to BDV in cats with neurological disease was higher than in cats with other types of disease, suggesting that the virus may play a role in nervous diseases of cats in the UK.

Mycobacterial disease in cats in Great Britain: I. Culture results, geographical distribution and clinical presentation of 339 cases

This study investigated 339 cases of feline mycobacterial disease from cats with cutaneous lesions or masses found at exploratory laparotomy. Tissue samples were submitted to the Veterinary Laboratories Agency for mycobacterial culture over a 4-year period to December 2008. The study assessed which species of culturable mycobacteria were involved, where the cats lived, and their clinical presentation (physical findings, serum biochemistry, radiography, feline leukaemia virus and feline immunodeficiency virus status). Mycobacterium microti was cultured from 19%, Mycobacterium bovis 15%, Mycobacterium avium 7%, non-M avium non-tuberculous mycobacteria 6%, with no growth in 53% of samples. M microti, M bovis and M avium were found in almost mutually exclusive clusters within Great Britain (GB) (ie, M bovis in South-West England/Wales/Welsh Border, M avium in eastern England and M microti south of London and in South-West Scotland). While differences were seen in the clinical presentation and distribution of lesions caused by the different infections, these were not sufficiently different to be diagnostic. Cats commonly presented with single or multiple cutaneous lesions (74%), which were sometimes ulcerated or discharging, located most frequently on the head (54%). Lymph nodes were usually involved (47%); typically the submandibular nodes. Systemic or pulmonary signs were rarely seen (10–16%). When a cat is suspected of having mycobacteriosis, accurate identification of the species involved helps to determine appropriate action. Our findings show that knowing the cats geographic location can be helpful, while the nature of the clinical presentation is less useful. Most cases of feline mycobacterial disease in GB are cutaneous.

Tritrichomonas foetus infection in cats with diarrhoea in a rescue colony in Italy

Faecal samples from 74 cats with chronic large bowel diarrhoea that were living in a rescue colony in Italy, were submitted for assessment of Tritrichomonas foetus by direct microscopy of faecal smears (n=20) and T foetus-specific culture (n=74), with confirmation by polymerase chain reaction (n=1). Twenty-four of the cats (32%) were found to be infected with T foetus. The infected cats were predominantly over a year of age (67%) and were all neutered non-pedigree domestic cats.

American Association of Feline Practitioners: Senior Care Guidelines

Background Cats are the most popular pet in the United States and much of Northern Europe. Although 78% of owners consider their cats to be family members, many cats, particularly seniors, do not receive appropriate preventive care.1–3 One of the main obstacles to owner compliance is the lack of a clear recommendation by the veterinary team. 4 Guidelines can help veterinarians to minimize this obstacle, strengthen the human-pet-veterinary bond, and improve the quality of life of cats. Goals The goals of this article are to assist veterinarians to: Deliver consistent high-quality care to senior cats. Promote longevity and improve the quality of life of senior cats by: recognizing and controlling health risk factors; facilitating and promoting early detection of disease; improving or maintaining residual organ function; and delaying the progression of common conditions. Define aspects of screening, diagnosis, treatment and anesthesia of senior cats.

Cobalamin, folate and inorganic phosphate abnormalities in ill cats

Hypocobalaminaemia in cats has previously been identified, but the incidence reported has varied, and the frequency of folate deficiency is unknown. The aims of this study were to evaluate the incidence of low cobalamin and folate levels in a population of cats that were suffering predominantly from diseases of the alimentary tract (including the liver and pancreas) and to ascertain whether severity of disease (as assessed by bodyweight and body condition score (BCS)) related to degree of deficiency. The study population comprised 103 cats, of which 16.5% had low cobalamin levels and 38.8% had low folate levels. A serendipitous finding was inorganic phosphate levels below the reference range in 48% of the cases. Significant associations were found between subnormal cobalamin levels and median BCS (P=0.049); combined low folate and low cobalamin and bodyweight (P=0.002), BCS (P=0.024) and inorganic phosphate levels (P=0.003). The finding of low levels of folate and cobalamin in clinical cases suggests that supplementation may be indicated more frequently than is currently recognised.
