ARM & HAMMER Clump & Seal Platinum Clumping Cat Litter is patented to absorb, seal, and destroy cat litter box odors on contact with 10% more odor eliminators than our regular ARM & HAMMER Clump & Seal Fresh Scent cat litter. No other litter brand forms an odor-containing seal around urine and feces and destroys sealed-in odors on contact with unique, powerful odor eliminators plus ARM & HAMMER Baking Soda. This clumping cat litter’s extra strength formula creates rock-hard clumps for easy scooping, and is powerful enough even for multi-cat homes.
