fip cats. Feline Infectious Peritonitis (FIP) is a serious, often fatal, viral disease affecting cats. FIP is caused by a mutated form of the coronavirus, which is highly contagious and can be spread through contact with infected cats, their feces, or other secretions. The disease affects multiple organs, including the liver, kidneys, and brain, and can result in death within a matter of days. There is no cure for FIP and no effective treatment available. Prevention is through good hygiene practices and vaccination of cats against coronavirus.
