It is of some interest that rabbit poop doesn't need to be composted, as does all other manure. Not quite sure how it manages to do that, but it may be that rabbits don't produce a lot of urine, and so the urea content of the poop perhaps is low. It's the urea that breaks down rapidly into ammonia, and can burn plants. It is a "cold" manure, rather than a "hot" one. But again, the nutrients are released slowly, so you don't get that NPK immediately. Many plants would rather have "right now" fertilizer.
