What is FIP/FCoV

Feline infectious peritonitis (FIP) is a viral disease of cats caused by certain strains of a virus called the feline coronavirus. 

Type one: 'dry' or non-effusive FIP where little to no fluid accumulates.  

Type two: 'wet' or effusive form of FIP, which refers to the accumulation of fluid in body cavities.


Cats that have been initially exposed to FeCV usually show no obvious symptoms. Some cats may show mild upper respiratory symptoms such as sneezing, watery eyes, and nasal discharge, while others may experience mild gastrointestinal signs such as diarrhea. In most cases, these mild signs are self-limiting. Only a small percentage of cats that are exposed to the FeCV develop FIP, and this can occur weeks, months, or even years after initial exposure to FeCV, infected cats can have symptoms of one form or a combination of both forms.


Many of the clinical signs of FIP are vague and occur with other diseases found in cats, making FIP particularly difficult to diagnose. There may be abnormalities in a routine blood analysis, but none is specific for FIP. 

X-rays may be helpful to determine the presence of fluid in the abdomen or chest. If fluid is present, some of it can be removed by tapping the chest or the abdomen. Analysis of this fluid at a veterinary laboratory can be particularly valuable, as few other diseases produce the same type of fluid that FIP creates

Veterinary laboratories provide tests that detect antibodies to feline coronavirus in the blood, but these tests are non-specific and cannot be used alone to diagnose FIP. Some laboratories provide tests such as polymerase-chain reaction (PCR) tests, which can detect very small amounts of the virus but no unique genetic sequence associated with FIP has been identified.  

"Currently the only way to make a positive diagnosis of FIP is by histological examination of affected tissue (or by post-mortem examination) by a pathologist at a laboratory. "


FIP has long been considered an untreatable disease. It wasn’t until recently that antiviral drugs were introduced to help treat FIP. These drugs are not yet approved by the Food and Drug Administration (FDA), and their long-term effectiveness is still unknown. 

More information and help can be found

Other FIP treatments may include supportive care, such as drainage of built-up fluid, and blood transfusions.

You should consult your veterinarian to help you decide which treatment option is best for your cat, however remember there are always options and resources you may have not come across. That being said, never give up on your search for treatments.
