Fresh Step advanced unscented clumping cat litter is formulated with naturally activated charcoal that starts fighting odor on contact with urine and feces. Fresh Step advanced unscented litter also contains high-quality clumping clay, which clumps tight for easy scooping and prevents stinky crumbles from being left behind. And, it is 99.9% dust free for cleaner surfaces, cleaner air and reduced tracking. Cleaning is fast and easy—just add more litter to your cat's litter box after you scoop.
