I've been looking at Natural Balance, Royal Canin, Holistic Select, Nature's Variety, and Blue Basics, but I'm open to suggestions. I'm admittedly hesitant towards Nature's Variety and Blue Basics. Nature's Variety includes clay which concerns me (should a cat even be eating clay?), and when I have fed Blue Buffalo Wilderness to my cat in the past, it gave him really bad diarrhea. So what grain-free, limited ingredient canned cat foot do you recommend? (Feel free to suggest a brand outside of what I have listed, but no raw please!) Thanks in advance! Trying to reduce the amount of stool along with stool odor and gas. (Vet has already checked him out to make sure he has no internal parasites or sicknesses.)
