Well, I've been reading more and more online, and, it doesn't sound like grains are a good idea at all. It was just a couple of the recipes in the book I have that called for oats or rice, but, I'm going to check with my vet still, but, it's not sounding good. I've only fed him oats today, so, it won't be that big of a deal to not feed them. I'll do more research, though, for sure.
