No matter how many cats you have, an odor-free home starts with Arm and Hammer Double Duty Cat Litter. It defeats pet waste odors in two ways, so your house always smells fresh and clean. First, powerful moisture-activated baking soda crystals boosted with feces odor neutralizers destroy urine and feces odors on contact. Next, the waste forms into rock-solid masses when you use this clumping cat litter, which allows you to remove the source of the odors easily. It's low-tracking too, so things stay tidy outside the litter box. For optimal health, this 99-percent dust-free cat litter, in 46-pound size, keeps dust out of your nose. It will fill the box many times over. Arm and Hammer Double Duty Cat Litter provides advanced odor control in an extra-large box, so you can relax.
