Feline Infectious Peritonitis (FIP)

What is Feline Infectious Peritonitis?

Feline Infectious Peritonitis is a fatal viral infection of domestic and wild cats caused by a specific strain of virus called feline coronavirus. Since it produces alpha coronaviruses in cats, it differs from SARS-Cov-2 coronavirus, which produces COVID-19, a beta alphavirus in humans. FCoV is found in both domestically kept and outdoor cats.  Infection rate increases dramatically in multi-litter household when compared to single cat households.

Although Feline coronavirus (FCoV) causes only mild diarrhoea in cats, its mutated strain can lead to serious illness that can lead to death in cats. About 10% of infected cats will develop an infection known as feline infectious peritonitis virus (FIPV) that can spread throughout their bodies. When it becomes progressive it starts involving the kidneys, abdomen, and brain.

What are the Clinical Signs of FIP?

Symptoms of feline infectious peritonitis are diverse and can make the clinical diagnosis based on symptoms
pretty hard. At the start, some vague symptoms are common. These include fluctuating fever, energy loss, and inappetence. After some time, cats can present with ‘dry’ or ‘non-effusive’ disease or ‘wet’ or ‘effusive’ disease.

Dry FIP or non-effusive FIP

It mainly causes inflammatory lesions around the blood vessels affecting the kidneys, liver, lungs, brain, and skin. The cats with the dry form of FIP can show the following clinical signs.

  • Seizures

  • Uncoordinated body movement

  • Excessive thirst and urination

  • Weight loss

  • Jaundice

  • Vomiting

Wet FIP or effusive FIP

In Wet FIP, inflammatory reactions affect the blood vessels causing vasculitis and fluid leakage from the blood into the chest and abdominal cavity. As a result, a large amount of fluid accumulates in the abdomen and chest, causing a pot-bellied appearance and difficulty breathing.

How can FIP be Diagnosed?

Symptoms of FIP are wide yet vague which makes it difficult to diagnose. Also, your veterinarian can not diagnose it based on only one blood test. Following factors can make the diagnosis easy if your cat:

  • Shows clinical signs of FIP

  • Falls in the high-risk groups (e.g., colony cats, colony cats, etc.)

  • Presents with yellowing of the eyes and gums


Based on laboratory tests, a cat affected by FIP can have:

  • Lymphopenia or decrease in the number of white blood cells

  • Neutrophilia or an increase in the number of neutrophils

  • Deficiency of blood

  • Increased concentration of proteins

  • High levels of liver enzymes and bilirubin


Besides, there are many other tests that can confirm its diagnosis. A few of them are:

  • X-ray and Ultrasound

  • Immunoperoxidase test

  • Polymerase chain reaction technology

  • Biopsy
