Walnut Shell Litter Wins Over a Seven-Cat Household

A cat owner with seven cats and nine litter boxes tested Naturally Fresh® Walnut Shell Cat Litter to see if it could meet her high standards for odor control, low dust, and clumping.
The walnut-shell product claims to neutralize ammonia at the source without added fragrance, produce very low dust, and form firm clumps that are slightly looser than clay but comparable to corn. It also has low tracking because the heavier granules stay in the box, and it lasts longer than clay and silica gel, roughly matching corn cob litter in longevity according to the reviewer’s multi-box testing. The litter is biodegradable and compostable; the brand states it is flushable but advises checking local rules.
The owner noted that the litter was well received by her cats, who did not immediately reject it, and that the brand’s formulas are non-toxic, made without harmful ingredients, and safe for kittens and small animals. The brand recommends setting a 15-minute delay in automatic litter boxes to allow clumps to form before the cleaning cycle starts.
Naturally Fresh offers several sizes, including a 26-lb multi-cat bag and a 14-lb quick-clumping option, available at PetSmart.
