Cat with FUO. What is likelihood it could be FIP?

Thanks for reaching out. I completely understand why you're worried about your cat's fever of unknown origin (FUO). When it comes to cats, FUOs can indeed be concerning because they can stem from various causes, including infections, inflammatory conditions, or even stress.



Feline Infectious Peritonitis (FIP) is one possible cause, but it's relatively rare and typically affects younger cats, especially those from multi-cat environments. FIP is caused by a specific mutation of the feline coronavirus, which is common but usually harmless in its typical form. Unfortunately, diagnosing FIP can be tricky without specific lab tests because its symptoms overlap with other diseases.



For now, monitor your cat’s overall behavior, appetite, and energy levels. Ensure they're drinking plenty of water and consider gently checking their temperature if they tolerate it. A full-body feeling for any unusual lumps or swollen areas might also be revealing.



Important signs of severe illness include persistent high fever, noticeable weight loss, difficulty breathing, or a bloated abdomen. If you observe these, it may be time to seek further consultation.



I recommend booking a video consult with one of our veterinarians at Dial A Vet. They can assess your cat's symptoms more thoroughly and guide you on the best next steps.
