FIP is no longer a death sentence. Today there are treatments available; you are not alone: here you will find information, support, and hope.

What is the FIP?
Feline Infectious Peritonitis
FIP (Feline Infectious Peritonitis) is a mutation of the coronavirus (FCoV).
Coronavirus is very common; between 80% and 85% of cats have it, and it usually doesn’t cause them any problems—maybe just a little diarrhea. It’s contagious and spreads through the litter box.
FIP, on the other hand, is NOT contagious and is a mutation that occurs in every cat, appearing in 5% to 10% of cases.
This mutation occurs within the cat following a prolonged period of stress and depends on its immune system or genetic predisposition. But since February 2019, with GS 441524, FIP is curable!

Frequently Asked Questions About Feline Infectious Peritonitis
Yes, FIP has been curable since February 2019, when Dr Niels Pedersen of the University of California, Davis published a study using GS-441524.
Although it was considered an incurable disease for years, FIP (feline infectious peritonitis) can now be cured thanks to antiviral treatments such as GS-441524. This medication acts directly against the virus that causes FIP and has helped thousands of cats recover worldwide, including many cases in Spain.
Treatment should be supervised by a veterinarian with experience in FIP and typically lasts about 12 weeks. The sooner treatment begins, the greater the chances of success.
On this website, we’ll tell you everything you need to know: how to access the treatment, which veterinarians offer it, and what to expect during the recovery process.
If a cat’s immune system is healthy and mature, white blood cells should fight off an infection or virus and allow the cat to develop an immune response or antibodies. Cats that develop FIP have an immune defect or deficiency that prevents them from fighting off the virus. Essentially, the cat’s immune system spreads the virus throughout the cat’s body via macrophages, rather than trying to eliminate it.
The nucleoside analogue GS-441524 is a molecular precursor of a pharmacologically active nucleoside triphosphate. These analogues act as an alternative substrate and RNA chain terminator for viral RNA-dependent RNA polymerase. In general terms, GS-441524 interferes with the chain reaction and prevents the virus from replicating.
