Has anybody had the experience that as soon as their cat started insulin they got diarrhea? After almost 2 months I can not get his diarrhea controlled...have tried pumpkin & probiotics. My vet says she has never seen this before. We also have not achieved diabetic control. He will not eat the diabetic diets & has had urinary issues in the past. Currently eats Royal Canin SO & several kinds of high quality/high protein wet foods.
