No IBD here, but we've been feeding Prowl, which is considered a raw diet. I like it because it's high-quality, grain-free, and dehydrated. That means no heavy cases of cans, and I can vary the water content when I rehydrate it (if, for example, our male's urine output seems low). I also like that our female can't pick chunks of it out of the bowl and fling it on the floor to eat, as she does with canned food
