FIP and gas don't really relate, but I do understand where she is coming from.. his belly probably has a jello-y feel to it. FIP hits hard and hit's fast.. and can affect basically any cat. It's always something to be on guard for.
Stick with the meds and limited diet. Geneflora is a pretty good probiotic that is readily available. Aunt Jeni's makes some good digestive probiotics as well.
My cat is smarter than your honor student.
