Feline Infectious Peritonitis is a devastating viral disease of cats that occurs worldwide and can affect many systems of the body. It is a progressive disease and almost always fatal. FIP affects domestic cats, especially purebred kittens: 70% of FIP cases are in pedigree kittens and cats. It is also a plague in rescue shelters and can be a danger to big cats kept in zoo environments. FIP occurs when the cat mounts an overly inflammatory immune response to feline coronavirus infection.
