FIP is now a curable disease!

Help my cat now »

Feline infectious peritonitis (FIP) is no longer a terminal diagnosis for cats. Thousands of people have been sucessfully treating their cats using the antiviral GS-441524 (GS for short). This antiviral treatment can be obtained by getting in touch with admins from various facebook groups dedicated to treating FIP. The main group for helping individuals gain access to GS is FIP Warriors. Ask to be added, and get in touch with an admin ASAP who will be able to help you purchase GS.

There are numerous brands of GS available. Admins in the group keep track of brands and treatment outcomes. This allows admins to help you treat your cat using brands likely to result in successful outcomes.

How much does it cost?

Although FIP is now curable, the treatment is not inexpensive. Costs will depend on your cat's weight and other symptoms. Typically, costs vary from around $2,500 to $8,000 for the duration of treatment. You can estimate the costs of treatment based on data that individuals like you have logged on this website.

Scientific Basis?

Researchers at the University of California-Davis have spent decades researching FIP. Up until their groundbreaking study that came out in 2019, FIP was largely regarded as a terminal disease in cats, with most vets recommending euthanasia. Since mid-2019, tens-of-thousands of cat owners everywhere have been able to cure their cats of FIP.

More FIP Research is needed


GS-441524 is not the end goal for treating cats with FIP. Everyone that has been through this process can attest that there needs to be something better. Injecting an uncooperative cat for 84 days is far from ideal. There is an organization, ZenByCat, which is setup to raise money for research to support finding a better treatment for FIP. If you have made it this far, please consider becoming a monthly donor to help find a cheaper, better way to treat FIP cats.
