Feline Infectious Peritonitis was once a near-universally fatal diagnosis, but antiviral treatments have transformed outcomes and represent one of veterinary medicine greatest welfare advances.
The emergence of effective FIP treatment represents a transformative welfare advance for cats — a condition that previously caused profound suffering and certain death is now survivable for most diagnosed cats. However, access disparities remain a welfare concern: many cats in lower-income households or countries cannot access treatment. Supporting generic access, insurance coverage, and subsidised treatment programs for shelter cats is a high-impact welfare intervention.
