When you rotate your cat's food do you give them a different brand/flavor every meal or do you give them the same kind for a while and then switch to another? How many different foods are in your rotation? I plan on feeding canned. The best deals I've found are online by the case. But most of those brands are not available in my area for me to buy a can or two to try. I figured maybe I would buy a few cans of what is available, taste of the wild, wellness, natural balance... and see if the cat is picky before I order a case of anything. Felidae is a good deal on amazon, so is taste of the wild, the big cans. Nobody here carries the big cans.
