Fight odor with the power you want, not the perfumes you don't. Our Free & Clean formula has no fragrances or dyes, helping your cat to feel at home in her litter box. Instead, we use activated charcoal to absorb odors for a neutral-smelling clean. Tiny pores on the charcoal's surface suck up odors on contact and trap unpleasant smells inside the charcoal's structure. The addition of Ammonia Blocker prevents ammonia odors from developing for at least two weeks* with regular maintenance, helping you stop lingering smells before they start. Dependable clumping action leaves behind tight clumps for easy removal, and TidyLock technology locks away odors to keep the litter box fresh between cleanings. Our unscented formula is low dust and weighs 50% less than clumping cat litter. That's a lot of ways to lighten your load without compromising on your cat's comfort.
