Although my kitten is stil being monitored and no firm diagnosis has been made, I think that my vet is leaning toward a diagnosis of Irritable Bowel Disease for him. If that turns out to be the case are there any good store-bought cat foods out there that are easy on his stomach? Doing a raw food diet is NOT an option for me right now, and I believe it would make things worse for him. He has already been on Royal Canin Gastrointestinal and Hill's W/D, neither of which seemed to change anything. The only thing that has ever "cured" him temporarily was treating him with Sulfasalazine. The loose stools came back about 2-3 weeks after stopping the medication. I'm not sure if a dietary change will help or not. I am currently feeding him Blue Buffalo Basics Limited Ingredient Fish and Potato (dry), and I have been told not to switch his food for now. That includes giving him canned. The reports about Blue Buffalo lately are alarming, but the food has worked wonders for my adult cat, who is no longer vomiting after eating. The kitten is back to having loose stools though. I have expressed my concern about Blue Buffalo to my vet, but she wants me to stick with it and swears by this food. You would think she has stock in the company or something! Blue Buffalo has a Sensitive Stomach food, but it has chicken and eggs, and I was told to avoid these foods because of my other cat. She has basically had me avoid any ingredients that could be potential irritants for both cats, including chicken, beef, corn, soy, wheat, eggs, and dairy. She seems to be against turkey and duck for now, too. She thinks that rice is okay though, and apparently fish is NOT bad? I'm so confused! Anyway, back to my original question: has anyone successfully treated their cat's loose stools or IBD with a commercial cat food (not raw)? Should I stick with Blue Buffalo Basics?
