My only worry about organ meat is how rich it is. I'm not sure how it works with cats who aren't used to raw, but it may give her diarrhea?
And yep - despite popular belief, it's the cooked bones that are dangerous, not the raw ones. (well.. technically speaking, raw bones can still be a choking hazard, but that's a given with bones of any kind)
