My older cat (the one whos tooth was pulled) had IBS and was on medi cal Hypoallergenic you have to buy it from the vet but it was the only thing that agreed with her. Was on a locally made raw food before the issues. You could try the medi cal but I can't guarantee it will work YMMV
This is just my cats but I found canned is easier on the digestive system than dry.
