Feline Infectious Peritonitis was once considered universally fatal, but antiviral treatments now offer affected cats a real chance at recovery and long-term survival.
FIP causes profound suffering through fever, weight loss, abdominal fluid accumulation, neurological symptoms, and progressive organ failure. The transformation of FIP from a death sentence to a treatable condition represents one of the most significant welfare advances in feline medicine. However, access to treatment remains challenging due to cost and regulatory status in some countries, meaning many cats still die needlessly. Advocacy for treatment access is a genuine welfare priority.
