Arm & Hammer Double Duty Clumping Cat Litter leverages the proven odor-neutralizing power of Arm & Hammer baking soda to address the root cause of litter box odor rather than masking it with perfume. Baking soda neutralizes the ammonia and organic acids responsible for litter box smell at the molecular level, while the clumping formula encases waste quickly and firmly for easy, clean scooping. The Double Duty formula targets both urine and feces odors specifically, which require different chemistry to neutralize effectively. The 7-day odor control guarantee reflects Arm & Hammer's confidence in the formula's sustained performance. No artificial perfumes means sensitive cats and owners avoid the overpowering fragrance that many cats reject. At twenty dollars for 20 pounds, it offers strong value for premium odor control. For multi-cat households or owners who cannot scoop multiple times daily, Arm & Hammer's baking soda formula provides the extra odor control needed.
