Nasopharyngeal disease in cats:2. Specific conditions and their management
Practical relevance: Nasopharyngeal disease is a common presenting problem in feline medicine. Clinical challenges: The management of feline nasopharyngeal disease can be challenging at a number of levels. In many cases, a specific diagnosis may remain elusive. Some conditions may not be curable so owners need to understand the requirement for long-term management. In addition, treatment may be compromised by poor patient compliance. Audience: This review, which is directed at any clinicians involved in the management of cats with nasopharyngeal disease, discusses acute rhinitis (cat ’flu) and a variety of conditions causing chronic rhinosinusitis/chronic nasopharyngeal disease. The intention is to assist treatment decision making by reviewing the most appropriate therapies from the options available for these patients. Evidence base: The information presented in this article is based on peer-reviewed publications and the clinical experience of the authors. </jats:p
How and why pet cats are fed the way they are:a self-reported owner survey
OBJECTIVES: This study used an owner-directed online questionnaire to collect data regarding their food and water provision for their pet cats. The survey was conducted in 2019.METHODS: The anonymous online 30-question survey was available via vetprofessionals.com.RESULTS: A total of 1172 cat owners fully completed the questionnaire. The respondents each owned a median of two cats (range 1-6). They reported being most strongly motivated to feed a particular ration because of palatability, observed and/or expected health benefits, or that the diet was/is perceived as 'natural'. The majority of owners (n = 946, 80.7%) fed their cats exclusively a commercially purchased complete wet food, dry kibble diet or mixture of both. Compared with a previous (unpublished) survey conducted by the same authors in 2013,1 there were substantial increases in the number of owners feeding therapeutic diets (26.6% vs 0.7%) and the inclusion of raw meat in cats' rations (15.6% vs 3.7%). The proportion of respondents providing at least one feeding station per cat was 83.1%, with significant use of enrichment feeding methods (29.1%).CONCLUSIONS AND RELEVANCE: Veterinarians need to be aware of changing trends in cat feeding to provide owners with appropriate support. Veterinary advice was frequently sought by owners and can be used as an opportunity to improve cat health and welfare, particularly in multi-cat households, but was not often influential to client decision making.</p
Disseminated Mycobacterium avium infection in a cat on long-term ciclosporin therapy and potential latent infection of an in-contact cat
Case summary:
An 8-year-old domestic shorthair cat receiving long-term ciclosporin treatment was evaluated for a history of weight loss and hyporexia. The main clinical finding was a cluster of enlarged mesenteric lymph nodes. Cytological examination of fine-needle aspirates showed granulomatous inflammation with abundant acid-fast bacilli. A diagnosis of Mycobacterium avium complex (MAC) infection was confirmed by PCR. The cat’s clinical condition deteriorated rapidly despite appropriate antibiotic treatment and it was euthanased 2 weeks after initial presentation due to development of severe paraparesis and ataxia. Post-mortem examination revealed granulomatous inflammation affecting multiple lymph nodes and other organs with intrahistiocytic acid-fast bacilli consistent with mycobacteria when stained using Ziehl–Neelsen stain. Another cat in the same household was screened for infection using the interferon gamma release assay (IGRA), with the result being consistent with infection by non-tuberculous mycobacteria (NTM), which includes MAC; however, it had no grossly detectable disease.
Relevance and novel information:
This case report is an unusual presentation of disseminated MAC infection in a cat, which remains a rare diagnosis. Clinicians should be aware of unusual and rare presentations of this infection. The clinical findings, progression of disease and histopathology results add to the current clinical database for feline disseminated MAC infections. Another cat in the same household tested positive for NTM by IGRA without any gross disease. This was suggestive of latent MAC infection which, to our knowledge, has not been previously reported in an in-contact cat
Use of computed tomography imaging during long-term follow-up of nine feline tuberculosis cases
Case series summary:
Feline tuberculosis is an increasingly recognised potential zoonosis of cats. Treatment is challenging and prognosis can vary greatly between cases. Pulmonary infection requires extended courses of antibiotics, but methodologies for sensitively monitoring response to treatment are currently lacking. In this case series, we retrospectively examined the serial computed tomography (CT) findings in nine cats that had been diagnosed with tuberculosis. Changes in pathology (where applicable to tuberculosis) were correlated with the clinical presentation of each of the cats, the treatment protocol, and previous and contemporary diagnostic investigations. This study found that changes in CT findings during the medium- to long-term management of feline tuberculosis were highly variable between cats. The majority of cats had reduced pathology at re-examination during anti-tuberculous therapy, but pathology only resolved in a minority of cases. In some cases recurrence of pathology detected by CT imaging preceded clinical deterioration, allowing for rapid therapeutic intervention.
Relevance and novel information:
When considered in combination with clinical findings, CT studies can aid in decision making regarding tapering of antibiotic protocols, or reintroduction of therapy in cases of recurrence or reinfection. This series also highlights that, in some cases, persistent abnormalities can be detected by CT, so complete resolution of CT pathology should not always be a goal in the management of feline tuberculosis
