Review on Arm & Hammer Naturals Clumping Litter: Double Duty with Corn Fibers - 9lb by Ashley Nelson

This smells the best of all the really healthy natural fillers out there right now. I chose this for the benefit of the Arm & Hammer and also for the clumping. You practically don't smell urine, even if you're standing next to a used box. If my cat ever covers up her human feces, I'm sure the same could apply to her. In its current form it is still excellent at eliminating this odor and is much easier to sift than with granular filling. It's a little dusty, but much less so than clay, and the overall benefits of this filler place it above all non-natural fillers. I have it on subscription and am saving now.
