The 2022 AAFP/EveryCat Feline Infectious Peritonitis Diagnosis Guidelines (published in the Journal of Feline Medicine and Surgery) aim to give veterinarians the information needed to reach an FIP diagnosis in cats. FIP is described as a viral disease that can affect any organ in the body, caused by the feline coronavirus (FCoV), and as fatal when untreated.
Because FIP is often hard to confirm, diagnosis is framed as building an index of suspicion of FIP brick by brick: it relies upon evidence from signalment, history, physical examination findings, and diagnostic testing rather than any single test. The guidelines compile detailed pathogenesis, diagnostic-testing considerations, clinical images, tables, and a supplemental library of videos and a printable health questionnaire.
Pet-food relevance is limited, but FIP and its differential list (including Feline infectious peritonitis among the disease fact sheets) intersect with the infectious-disease and retrovirus topics in this category. Written in paraphrase mode (AAFP/SAGE copyrighted); exact guideline title, the FCoV causation statement, and the diagnostic-evidence wording are anchored verbatim.
