How to Diagnose FIP in Cats

Feline Infectious Peritonitis (FIP) is a viral disease that affects cats, particularly those with weak immune systems. It is caused by a coronavirus and can be challenging to diagnose due to its non-specific symptoms. However, early detection is crucial for the well-being of your feline friend. Here are some ways to diagnose FIP in cats:

1. Clinical Evaluation: A veterinarian will conduct a thorough examination of your cat, considering their medical history and symptoms. Common signs of FIP include weight loss, fever, lethargy, and fluid accumulation in the abdomen.

2. Blood Tests: Blood samples can be analyzed to detect the presence of specific antibodies or proteins associated with FIP. However, these tests are not always conclusive and may require further confirmation.

3. Fluid Analysis: If your cat exhibits symptoms of fluid accumulation, the fluid can be analyzed for protein levels and the presence of coronavirus. High protein levels and the presence of the virus can indicate FIP.

4. Biopsy: In some cases, a biopsy of affected organs may be necessary to confirm FIP. This involves extracting a small tissue sample for laboratory examination. Biopsies can be invasive and are typically performed as a last resort.

5. Polymerase Chain Reaction (PCR) Test: PCR tests can detect the genetic material of the FIP virus. This test is highly accurate and can be useful for diagnosis. However, it may not always be readily available in all veterinary clinics.

6. Imaging: X-rays or ultrasounds may be conducted to assess organ damage caused by FIP. These imaging tests can provide valuable information about the disease’s progression.

7. Medical History: A thorough review of your cat’s medical records and any previous illnesses can help in the diagnosis of FIP. Cats that have been exposed to coronavirus and have a weakened immune system are at a higher risk.


1. Can FIP be cured?
Unfortunately, there is currently no known cure for FIP. Treatment usually focuses on supportive care to manage symptoms and improve the cat’s quality of life.

2. Is FIP contagious to other cats or humans?
FIP is caused by a mutated strain of the coronavirus, which is not highly contagious to other cats or humans.

3. Can FIP be prevented?
Preventing FIP can be challenging. Reducing stress, maintaining good hygiene, and vaccinating against the feline coronavirus can help lower the risk.

4. Can FIP affect cats of any age?
FIP can occur in cats of any age but is more commonly seen in young kittens or older cats with weaker immune systems.

5. Is FIP fatal?
Unfortunately, FIP is a fatal disease. It is estimated that 95% of cats diagnosed with FIP do not survive beyond a year.

6. Can FIP be misdiagnosed?
FIP can be challenging to diagnose accurately due to its non-specific symptoms. However, with a combination of clinical evaluation and diagnostic tests, the accuracy of diagnosis can be improved.

7. Can FIP be transmitted through sharing litter boxes or food bowls?
The FIP virus is primarily spread through close contact with an infected cat’s bodily fluids. Sharing litter boxes or food bowls does not pose a significant risk of transmission.
