Arm & Hammer Double Duty is a clumping clay litter built around odor control, using the brand's baking soda and Clump & Seal technology to trap smells inside the clump. It is marketed for multi-cat homes and claims 7-day odor control and 99.9% dust-free pouring. Against rivals, it competes with other baking-soda litters like Arm & Hammer's own Clump & Seal lines and with premium clumping litters; it is a solid mid-tier pick for scooping households that want firm clumps and odor blocking without a specialty litter.
