Just wanted to put my $.02 into the fert litter discussion. I have great luck with recycled newspaper litter. Its called "Yesterday's News" and comes in 2 sizes of small pellets, looking much like rabbit food pellets. It absorbs very well, so a little goes a long way. It has no dust and is flushable, a definite plus. Rob McNish and the gang at McFerret Acres [Posted in FML issue 1925]
