ARM & HAMMER Double Duty Clumping Cat Litter 20 lb

"After trying five litters this year alone, I finally found one that actually eliminates odors instead of masking them." The ARM & HAMMER Double Duty Clumping Cat Litter has earned that kind of loyalty among cat owners who've grown weary of the same old stories — foaming litter that doesn't absorb liquid fast enough, powdery litters that blow across the floor like snow, formulas that claim elimination but still leave a faint, lingering scent in the room. Double Duty is different from the start. Its moisture-activated microgranule technology goes to work the moment liquid hits the surface, locking away both urine and feces in firm, easy-to-lift clumps so you're never wrestling with loose, crumbly material. That's dual odor control working in concert — urine odor neutralized on entry, fecal odor handled as a separate challenge once it's trapped inside a firm, dry clump. The result is a noticeably fresher litter box environment after just a few days of regular use. Baking soda forms the heart of the formula — 99.9% dust-free, with low tracking so less goes everywhere else in the house. At 20 lbs per bag, it's a practical size for households with one cat or those who prefer to stock up rather than make weekly trips to the store. The hard, round clumps lift cleanly from the pan, making scooping fast and hygienic — a small ritual that feels genuinely less unpleasant when it takes seconds rather than minutes. If you're comparing this against other clumping litters, the standout here is the depth of odor control rather than the surface appeal. Where competitors rely on fragrance or enzyme reactions, Double Duty addresses the problem at its source. It's a straightforward, effective formula from a trusted name in pet care — ARM & HAMMER — with a track record that spans decades of household cleaning innovation.
