About Feline Infectious Peritonitis (FIP)

Feline infectious peritonitis (often called FIP) is a severe, usually fatal disease caused by a feline coronavirus. The disease is seen worldwide. Cats of all ages and either sex can develop feline infectious peritonitis, but the disease is most frequent in cats 6 months to 2 years old. Although the disease can occur in any breed, purebred cats (including Persian, Abyssinian, Bengal, Birman, Himalayan, Ragdoll, and Rex breeds) are most likely to be affected.

    The signs of feline infectious peritonitis vary depending on which organs are involved. Many organs, including the liver, kidneys, pancreas, CNS, and eyes, can be affected. The length of time between infection and mutation of the virus and development of signs varies between cats. Affected cats may be alert or depressed. Some eat with a normal or even increased appetite; others refuse to eat. Fever, weight loss, and/or jaundice may be noted.

    FIP displays in a “wet” form and a “dry” form. Signs of both forms include fever that doesn’t respond to antibiotics, anorexia, weight loss and lethargy. In addition, the wet form of FIP is most known for the accrual of fluid in the abdominal cavity, the chest cavity, or both. Cats with fluid in the chest experience labored breathing. Cats with fluid in the abdomen show increasing, nonpainful abdominal distension.
