FIP was once a fatal diagnosis in cats, but new antiviral treatments have transformed outcomes for thousands of cats.
The development of effective FIP treatment represents one of the most dramatic welfare advances in companion animal medicine. Cats that would previously have died within weeks now achieve sustained remission with antiviral therapy. However, the cost of treatment — often thousands of dollars — places it out of reach for many owners, creating a painful welfare inequality. Advocacy for accessible treatment and support for cats whose owners cannot afford therapy are important welfare priorities.
