ARM & HAMMER Cat Litter Deodorizer is an odor eliminator that helps your litter box stay first-day fresh longer than cat litter alone. As the #1 cat litter deodorizer brand*, it’s made with ARM & HAMMER Baking Soda Crystals to destroy tough urine odors on contact. Its moisture-activated scent refreshes every time your cat uses the litter box. In fact, internal lab tests demonstrate that it lowers odor levels after 9 days compared to clay, scoopable or natural—scented or unscented—cat litter alone. When used regularly, ARM & HAMMER Cat Litter Deodorizer is absorbent to help prevent litter clumps from sticking to the box. This cat litter deodorizer is safe for cats and owners to use every day when used as directed. Just sprinkle it in to deodorize any type of cat litter—scented, unscented, clay, scoopable, or natural. *Based on Units Sold, Nielsen Total U.S. AOC, L52wks ending 06/05/21
