So Gigi was on kibble for breakfast and medallion for dinner before she was sick 2 weeks ago. And since then she is on ID canned food (prescription). The vet said she can be on it forever if I want to. Because Miss Gigi has sensative tummy. So should I just let her be on it? Or should I switch back? She seems to like her canned food, so I don't know what I want to do about it.
