Rebecca Coleman was asking about using wood pellets for the litterbox. We put a SMALL amount of clumping (scoopable) cat litter in the bottom of the box and then put a nice thick layer of processed corn-cob ($2 for 10.1 liters). We've been doing this now for two-and-a-half weeks with very good results - no clumps of litter in the nose or butt and very easy to scoop after each use. Hope it helps!
