The Gentle Touch Pet Litter (aspen wood pellets) is WONDERFUL!!!  I tried
it with my ferrets (I have 17) and it GREATLY reduced the litterbox odors.
And with 17, that's a significant reduction!  Note, they have two sizes of
pellets - the larger size is appox the size of the oak woodstove pellets.
The smaller size is comperable to Pet Fresh pelleted pine cat litter.  Also
remember, when you use a wood pelleted litter, only fill the litterbox
approx 1/4 full as the litter will expand to double its original size.  Any
more than that and you may have an overflow problem.
