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.
