Hi Catnapper! Please try not to worry about little Angeleyes and FIP. When Groucho was 5 months old our vet at the time did a series of tests in preparation of having him neutered. She called a few days later and said Groucho tested positive for FIP but she said since he was less than 6 months old it was possible that he tested positive for his mother's antibodies. Because of his age, doctor said she wanted to test him again 6 weeks later. Took him in, doctor did the test and a few days later she said the results were down but not quite where she wanted to see it. She tested him again 6 weeks later and the results were great, right where they should be. I really don't know much about FIP. only that the vet can only treat the symptoms. Anyway, if you think she's showing symptoms and your vet wants to do a test remember to ask if she could be testing positive for her mother's antibodies. Just wanted to try and ease your mind as well as give you something to ask your vet if it should become necessary. Will you give Flutter and Angeleyes a couple tons of lovebug from me? And please let us know what happens.....
