This might sound funny but I am serious. The Manure thread made me think of this question. Can I safely compost my pet rabbit's potty box? She is supplied with pine pellets and uses the potty pretty much exclusively. Can I compost something that includes her urine? How about the pine shavings below. Often there are rabbit droppings there, but also alfalfa pellets, and other rabbit food delights. Could I be possibly tossing out valuable yard material in our trash each week??
