Papurr Premium Cat Litter 1

I switched from clay litter for health reasons to avoid the dust. I've tried all the sustitutes, corn, wood pellets, paper, etc, and to date this is the very worst litter. I have multiple cats, and a self cleaning litterpan. The cats quickly refused to continue using it due to the strong urine odor; it did not clump at all, and the pan could not dispose of it. The urine just went to the bottom of the pan and puddled there. Worthless, at least for multiple cats.
