Sodium bentonite naturally exhibits the scent-trapping properties of baking soda, so there’s no need to add chemicals or perfumes. It forms hard, tight clumps fast and locks in odor by drawing up liquid and isolating that telltale ammonia smell. We take great care to preserve these qualities during the drying and sifting process, so you can be sure there’s nothing better for your cat or your cat’s litter box.
