Fresh Step Extreme Scented Litter is formulated with the power of Febreze to help destroy extreme litter box odors. This low-dust litter formula with Ammonia Block technology helps control the growth of bacterial odors and blocks urine odors, leaving behind a Mountain Spring scent. The paw-activated fragrance releases every time your cat uses the litter box, providing odor control as needed without being overpowering. Plus, ClumpLock technology quickly absorbs liquids while trapping odors on contact to help form tight clumps and make scooping fast and easy.
