The transformation of FIP from 100% fatal to 85% treatable by GS-441524 represents one of veterinary medicine's greatest welfare advances, but access inequity remains a critical concern.
The FIP treatment revolution is one of the most profound welfare advances in companion animal medicine - a previously untreatable, uniformly fatal disease now has a cure. However, access to this cure remains tragically inequitable. Cats owned by families who cannot afford licensed treatment still die from a curable disease. This welfare gap drives the use of unlicensed formulations of varying quality. Advocacy for affordable licensed access and veterinary charity support for treatment costs are direct welfare interventions.
