Pet's info: Cat | Domestic Shorthair | Female | spayed | 6 months and 11 days old
My cat had diarrhea about 2 weeks ago.Her appetite/energy was normal and she only had fever the day before she started antibiotics. Vet said she has intestinal parasites, gave her medicine for 3 days. Her poop got better but her right eye got cloudy.So vet decided to run a fip test and gave terramycin for her eye and it healed.But results came positive for corona (elsa test).Vet said the symptoms means she has fip but she beat the disease but it can be active in the future again.Is it possible?

Many cats have Coronavirus. Once Coronavirus mutates into FIP (Feline infectious peritonitis) it is fatal and doesn't resolve. You can have a positive Coronavirus but that does not mean Mia has FIP. I have also seen a negative Coronavirus test and a cat end up with FIP. The only was to diagnose FIP is on necropsy. If Mia is positive for Coronavirus, yes it can mutate under stressful situations at any point. There are two different types of FIP. There is a dry form and a wet form. The dry form is difficult to diagnose since it typically presents as a high fever and a cat losing weight and not doing well. The wet form is easier to determine since they present with fluid in their abdomen and usually with liver disease. They also are icteric (have a yellow appearance to them). I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
