What is FIP Cat?

FIP Cats or Feline Infectious Peritonitis is a disease caused by the mutation of Feline Coronavirus (FCoV) in cats. FCoV is a type of virus that can spread through the saliva, feces, and urine of infected cats. It can also be transmitted to other cats through contact with environments contaminated by the virus. However, FCoV is not fatal and does not cause significant sickness to the infected cat. When FCoV mutates into FIP, it becomes very fatal to the infected cats.

The symptoms of FIP in cats vary depending on the form of FIP the cat is experiencing. There are two forms of FIP : 

  • Wet FIP

  • Dry FIP


If not treated promptly, both forms of FIP can progress into:

  • Neurological FIP

  • Ocular FIP

FIP in Cats Symptoms

The symptoms of FIP in cats can vary depending on the type of FIP.  Wet FIP is the more common form and is characterized by fluid accumulation in the abdomen or chest. Symptoms of this form of FIP include weight loss, loss of appetite, vomiting, diarrhea, and difficulty breathing.

Some common symptoms of FIP in cats include:

  • Fever

  • Lethargy

  • Loss of appetite

  • Drastic weight loss

  • Vomiting

  • Diarrhea

  • Difficulty in breathing

  • Fluid buildup in the abdomen (Wet FIP)

  • Jaundice

  • Anemia

In certain conditions, late FIP treatment can lead to other symptoms, such as neurological symptoms such as paralysis or seizure (neurological FIP) or cloudy eyes (ocular FIP).

Diagnosing FIP in Cats

Diagnosing FIP in cats can be difficult, as the symptoms can be similar to those of other diseases. To confirm a diagnosis of FIP in your cat, several tests should be performed. These tests include:

  • FCOV AB Test: This test looks for antibodies to the virus that causes FIP.

  • Rivalta Test: This test is performed if there is fluid accumulation in the abdominal cavity.

  • Hematology and Chemistry Blood Tests: These tests help to confirm levels of albumin, globulin, liver and kidney values.

  • Ultrasound (USG): This test is used to confirm fluid in the abdominal cavity.

Preventing FIP in Cats

The best way to prevent FIP in cats is to keep them in a clean and healthy environment. This means keeping their litter boxes clean and making sure they have access to fresh, clean water. It is also important to keep cats up to date on their vaccinations, as this can help reduce the risk of FIP.

It is also important to keep cats away from other cats that may be infected with FIP. If your cat does come into contact with an infected cat, it is important to keep a close eye on them for any signs of illness.

Diet and Nutrition for FIP Cats

Diet and nutrition play an important role in managing the symptoms of FIP in cats. It is important to feed your cat a well-balanced diet that is high in protein and low in carbohydrates. Fresh, raw food is best, as this provides the most nutrients for your cat.

It is also important to feed your cat food that is specifically designed for cats with FIP. These diets are formulated to provide the nutrients that cats with FIP need to stay healthy.


It is also important to make sure that your cat is getting enough water. Cats with FIP tend to become dehydrated easily, so it is important to provide them with plenty of fresh, clean water.

What is Wet FIP In Cats?

Dry FIP is another type of FIP disease. Dry FIP, unlike wet FIP, progresses without fluid accumulation in the cat's body. Instead, hard, nodal structures called granulomas form on the cat's body. These granulomas can cause damage to the cat's organs and tissues. The course of dry FIP is usually slower and its symptoms less severe. However, dry FIP can also cause serious health problems and reduce the cat's quality of life. The cause of dry FIP, like wet FIP, is related to the cat's immune system.

What is Dry FIP In Cats?

FIP is a feline disease called Feline Infectious Peritonitis. Wet FIP is the most common and dangerous type of this disease, often occurring in kittens between the age of 6 months to 1.5 years old. Wet FIP results in fluid accumulation in the cat's abdominal and thoracic cavity. This liquid is usually yellowish and sticky, causing discomfort by lowering the cat's body temperature.
