Abstract
Inheritance of susceptibility to feline infectious peritonitis was investigated with pedigree data from 10 generations of cats in purebred catteries. Cats that were first degree relatives of FIP-affected cats were significantly more likely to be affected by FIP than unrelated cats. It was often possible to trace inheritance of FIP in Persian catteries back to a particular ancestor. The mode of inheritance was best modeled as a polygenic trait. The heritabilities were very high: greater than 54% in four Persian catteries and 52% in one Birman cattery. Cat breeders might achieve success in reducing FIP risk by selecting cats from less susceptible lineages for their breeding programs.
