The 84-day GS-441524 protocol follows a predictable clinical arc for most cats. Knowing what to expect at each stage — what improving looks like, what warrants concern, and when blood work should confirm progress — helps owners stay informed and act quickly when something needs attention.

FIP is no longer a death sentence. GS-441524 achieves a 94.7% success rate when used correctly. But the outcome depends on more than just having the right drug — it depends on early diagnosis, correct dosing, reliable drug delivery, consistent monitoring, and completing the full protocol. This guide covers what actually moves the needle.

Multi-cat households have significantly higher FCoV prevalence than single-cat homes. That does not mean FIP is inevitable — but it does mean the steps you take around litter hygiene, stress management, and new cat introductions matter more. This guide covers the practical measures that actually reduce FIP risk.

Daily monitoring during FIP treatment is not optional — it is how you know whether GS-441524 is working, catch problems before they escalate, and give your vet the information they need to make good decisions. This guide covers exactly what to track, how to track it, and when to act.

FIP and feline lymphoma share many of the same symptoms — fever, weight loss, lethargy, fluid accumulation. Misdiagnosis is common and the consequences are serious. This guide explains the key clinical differences, which diagnostic tests distinguish them, and why getting it right determines whether your cat receives effective treatment.
