I know grains aren't naturally part of a cat's diet, so I've been looking at grain-free foods. There are a couple of high-protein, grain-free dry foods that I'd like to try out for my cats. However, dry food needs some sort of starch to hold the kibbles together, so they either contain potatoes or tapioca for that (which are not grains, but neither are part of a cat's natural diet either). I was wondering which one would be preferable for bengals? I read that potatoes are bad for cats and the tapioca foods specifically advertise that they are potato-free. But is tapioca any better?
