How often do you give tripe? It looks like I am going to be getting my freezer back at the end of January and I'm toying with the idea of putting Frodo back on all raw since he's having such a terrible time with allergies lately. I was just wondering how often you give tripe, and how much is too much tripe? Now I just need to decide whether I want to do frankenprey or ground. Ground is cheaper, but frankenprey is so much more fun!
