A lot can happen in a week, but smelling your cat’s litter box shouldn't be one of them. With our ARM & HAMMER Clump & Seal Platinum clumping cat litter odor-control product, it won't be. Our patented-formula ARM & HAMMER litter can absorb, seal, and destroy cat litter-box odors on contact and is effective enough to be used in a multiple-cat litter box. Moisture-activated Micro- Granules form a tight seal around odor and destroy it, while the litter helps create rock-solid cat litter clumping. With 10% more odor eliminators than our regular ARM & HAMMER Clump & Seal Fresh Scent cat litter—plus ARM & HAMMER baking soda—odors don’t stand a chance, and your kitty’s box can stay fresh for 14 day odor control guaranteed. For over 165 years, people have trusted the ARM & HAMMER brand for a range of versatile, effective household products. In 1992, they introduced their signature cat litter, made with odor-absorbing baking soda, to give pet parents an effective solution for litter box odor.
