Cat Litter, Large-Grain Formula 10 lbsOUTSTANDING ODOR CONTROL: Our proprietary formula instantly traps urine odor and prevents its build up. And we never use fragrance, so there are no artificial scents that can irritate both cats and people. EXCEPTIONAL CLUMPING: Because our litter is made exclusively from corn and cassava, its naturally rich in starches. This results in dry, fast forming, and firm clumps that you can trust to stay together while scooping and cleaning your litter box.
