FIP was once considered uniformly fatal, but newer antiviral medications such as GS‑441524 have made successful treatment and remission possible for many cats.

Most antiviral treatment protocols last between 6 and 12 weeks. Your cat’s specific situation, response to treatment, and follow‑up testing will help guide the exact duration.

GS‑441524 is an antiviral drug that targets the virus responsible for FIP. It helps reduce viral replication and inflammation, allowing the cat’s body to recover and heal.

Outcomes depend on the type of FIP, how advanced the disease is at the time of diagnosis, and how quickly treatment is started. Many treated cats go into remission and enjoy a good quality of life.

Yes. Because we are one of the only hospitals in Las Vegas that carry the GS-442415 drug in stock, we welcome referrals from other veterinarians and are happy to coordinate with your primary care vet to support FIP cases.

If your cat has been diagnosed with FIP or you suspect FIP based on concerning signs such as persistent fever, weight loss, fluid buildup, or neurological changes, contact us as soon as possible. Early evaluation and timely treatment can make a meaningful difference in your cat’s outcome.
