Feline infectious peritonitis
Feline infectious peritonitis (FIP) is a severe immune-mediated disease that follows mutation of a common feline enteric coronavirus into a virulent form. It most often affects young cats and those in multi-cat environments. Classic forms are an effusive (wet) type with fluid in the abdomen or chest and a dry (granulomatous) type. Once almost uniformly fatal, FIP is now treatable with antiviral therapy in many cases.
