Fresh Step Advanced Extreme clumping cat litter destroys extreme odors with the power of Febreze. It gets rid of the strongest litter box odors with a tough odor eliminating formula and leaves behind a fresh Mountain Spring scent. Fresh Step Advanced Extreme also uses Fresh Step Clumplock Technology, which locks in liquid and odor and creates tight clumps 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. Fill your clean litter box with 3–4 inches of Fresh Step® litter. Litter quickly forms a clump around liquid waste. Remove clumps and solids daily, and dispose of in trash. Do not flush. Add more Fresh Step® clumping cat litter to refresh your litter box. Maintain level of litter at 3–4 inches.
