Kirsten,

I wouldn't worry too much. MooShoo was also exposed to the FIP virus. He doesn't HAVE it though. There are two types, the wet type which is the kind that is contagious and the dry type which just means your cat exposed to it. Moo is healthy as a horse. In fact, he IS a horse!! All 15 pounds of him.

As long as Luna is eating, pooping, drinking and acting normally, don't worry.
