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. Chris [Posted in FML issue 2337]
