Arm & Hammer Double Duty is a clumping clay cat litter sold in a large 29 lb box. It pairs a clumping litter with baking soda and a deodorizing additive, so it targets odor control as much as clumping. It suits multi-cat homes and owners who want a simple scoop-and-top-off routine. Against premium litters it clumps less firmly and kicks up more dust, but it costs far less per pound and is widely available.
