I am so sorry Lizzie. FIP is the worst of the worst for our kitties. All I really know about it is that the test that they run to see if they have it, is really not that reliable. They are sometimes wrong, and sometimes it takes a few tries.... I would not depend on the test, IMO.

I would just be careful, and look for the symptoms to arise. And I know how careful you are with trying not to pass it along. Keep your head up, and I will pray for these babies...
