Feline Infectious Peritonitis (FIP) is a disease that kills 1 in 100 to 1 in 300 of all cats under ages 3-5. The incidence can be five to 10 times greater among young cats coming from catteries and shelters. FIP is virtually 100% fatal, and there is no treatment or cure. FIP can manifest suddenly -- weeks, months or even years after initial infection. Therefore, cat lovers usually experience the heartbreak of this disease long after they have developed strong emotional bonds with their pets.

UC Davis Cats for Adoption 2018

These four cats were pioneers in the FIP Studies at UC Davis and are being offered for adoption. They deserve to find good homes in gratitude for their contributions to the UC Davis anti-FIP virus drug studies. The cats are large with great dispositions, and Dr. Pedersen himself has adopted three of the cats from this group. If you are interested in adopting, please contact Maria at UC Davis at This email address is being protected from spambots. You need JavaScript enabled to view it. for more information.




UC Davis Feline Infectious Peritonitis Therapeutics/Clinical Trials Team

UC Davis FIP Research field trials have completed, and they are no longer accepting cats for treatment. The two drugs that have been researched both show great promise. They are now in various stages of being commercialized. It could take one or two years before any of these drugs are approved by the FDA and made available for use by licensed veterinarians, therefore these drugs will not be available to the public until the FDA process is complete. For more information about the outcome of the drug studies follow the links. There will be further publication regarding the latest study forthcoming as well.
