Over the last few years great progress has been made in the treatment of feline infectious peritonitis (FIP). This previously deadly disease in cats can now be successfully managed with proper treatment.
The disease that continues to perplex and challenge veterinary professionals worldwide. With no access to legal treatment for veterinarians in the U.S., FIP was often seen as a death sentence for cats. However, recent advancements in antiviral therapy have shown that effective treatment for Feline Infectious Peritonitis (FIP) is now a reality.
FIP is a severe disease in cats caused by feline coronavirus. COVID-19 is also caused by a coronavirus but the coronavirus causing FIP is not the same and only infects cats. Feline coronavirus is commonly found in the feces of cats and research has shown that infection is very common among cats. Thankfully, in most, it causes mild diarrhea or no signs at all. However, in a small number of cats, the virus changes (mutates) inside the cat, and interacts with the cat’s immune system in a certain way, resulting in FIP. Finding coronavirus in a cat doesn’t mean they have FIP, and it is not possible to consistently tell the difference between a coronavirus causing FIP, and one causing no signs of illness. Further tests must be performed by a veterinarian to diagnose FIP.
Many cats have a combination of ‘wet’ and ‘dry’ forms of FIP and some cats have pale, slightly yellow gums.
Cats with FIP can show a variety of signs as the disease can affect any organ in the body. The most common signs are:
We do not know why certain cats develop FIP and others do not, but it is diagnosed more often in:
Previously, there was no effective treatment for FIP but there are antiviral medications available now with good results in treating FIP. These drugs are legally available in many countries and have been proven safe and effective.
Current recommendations are to treat for 12 weeks to allow full clearance of the disease and give cats the best chance of recovery. Shorter courses may be recommended in the future as treatments advance. Different types of FIP require different amounts (dosages) of antiviral medication, cats showing neurological FIP and/or ocular FIP are often treated with higher dosages.
However, there is variation in how cats respond, and adjustments may be needed during the treatment period. If a cat is not responding as expected, the amount of antiviral medication may need to be increased.
