Feline Infectious Peritonitis in the Modern Era: Diagnosis, Antiviral Treatment, Monitoring, and Recovery

# Feline Infectious Peritonitis in the Modern Era

## Diagnosis, Antiviral Treatment, Monitoring, and Recovery

**By Kimberly Watson**

Feline infectious peritonitis used to be a diagnosis spoken in the language of inevitability. Today, antiviral treatment has changed the conversation—but it has also created a new problem: owners and caregivers must navigate rapidly evolving evidence, complicated testing, variable drug access, demanding treatment schedules, and a flood of confident advice that is not always reliable.

**Feline Infectious Peritonitis in the Modern Era** offers a clear, sober guide to that new landscape. It explains how feline coronavirus differs from FIP, why diagnosis is rarely based on a single test, how effusive, non-effusive, ocular, and neurological disease can present, and what modern antiviral treatment is designed to accomplish.

Inside, readers will learn:

- How FIP develops and why most feline coronavirus infections never become FIP - Why diagnosis depends on patterns of evidence rather than one definitive screening result - What GS-441524, remdesivir, molnupiravir, and protease inhibitors do—and where the evidence and uncertainties differ - How veterinarians assess treatment candidacy, route of administration, monitoring, adverse effects, and relapse risk - Why neurological and ocular FIP often require different clinical reasoning - What meaningful improvement looks like during treatment and what warning signs deserve prompt attention - How post-treatment observation helps distinguish durable recovery from relapse - How to communicate with a veterinary team, evaluate medication sources, and avoid dangerous shortcuts

This is not a miracle-cure pitch or a substitute for veterinary care. It is a practical framework for understanding the science, asking better questions, and making informed decisions with a qualified veterinarian. The tone is hopeful without being careless, technical without becoming inaccessible, and candid about the limits of current knowledge.

For cat owners facing a frightening diagnosis, veterinary professionals seeking an organized overview, and caregivers trying to separate evidence from rumor, this book provides the context needed to move from panic toward a disciplined plan.

Modern FIP care is no longer defined only by loss. It is defined by early recognition, responsible antiviral use, careful monitoring, and informed persistence.
