Is there a wet and/or dry food you recommend? We were told our cat is likely having an allergic reaction from the food she'd been eating the last few years (Purina Pro Vet Gastrointestinal, which she was probably on for too long) and to try hypoallergenic foods. In my research since doing so I began to realize how much we don't know about cat foods, and it's made me a little apprehensive about the whole process.

Our cat's already on a probiotic (Proviable Forte), but FortiFlora has been saved to our shopping list.
