Our take on the Arm & Hammer Clump & Seal Platinum Cat Litter, 40 lb

Clump & Seal Platinum is Arm & Hammer's premium clumping clay litter, built around moisture-activated micro-granules and baking soda for odor control. It forms hard clumps for easy scooping and is marketed as 99.9% dust-free with a 14-day odor guarantee. The fresh scent and fine granules suit multi-cat homes that want strong odor blocking, though some owners find the scent strong and the litter tracked. It competes with other premium clumping litters on odor control and low dust rather than on price.
