Worthing KA, Wigney DI, Dhand NK, et al. Risk factors for feline infectious peritonitis in Australian cats. J Feline Med Surg 2012;14:405-412.
The purpose of this study was to determine whether patient signalment (age, breed, sex, and neuter status) is associated with naturally-occurring feline infectious peritonitis (FIP) in cats in Australia. FIP is a feline coronavirus-induced disease. There have been several risk factors discussed in association with the development of FIP. The disease is more frequent in cats less than 2 years of age, cats that reside in multi-cat environments, and in pedigreed cats. Early studies suggested FIP has a bimodal age distribution, though recent studies do not support this observation. In this study, the patient signalment of 382 confirmed cases of FIP were compared with a general cat population. Younger cats were significantly over-represented among FIP cases and a bi-modal age distribution was not found. Pedigreed cats were significantly over-represented and domestic crossbreeds under-represented in FIP cases. Several breeds were over-represented, including British Shorthair, Devon Rex, and Abyssinian. Male cats had a significantly higher proportion of representation than female cats. Domestic crossbred, Persian, and Himalayan cats were significantly under-represented in the FIP cohort of this study. [VT]
