@Twice - After doing a quick search on the Yahoo group, there is some discussion on kidney failure. Didn't read a whole lot of it, but it looks like a good starting point if you want to go the raw route. There's a few who've experienced it with their dogs. If you want to go that way and scared of bones, I'd grind everything, even though it's not really the 'recommended' way for whole prey feeding. Doing what your heart and guts tell you is always what I always follow.
