Fresh Step Clean Paws Multi-Cat Clumping Cat Litter is formulated with the power of Febreze to destroy even the busiest litter box odors, leaving behind a fresh, clean scent. Made with larger, premium clay particles, this litter stays inside the box to help keep paws and your floors clean. Ammonia Block Technology helps control odors for up to 10 days. Working in two ways, this technology controls bacterial growth, while also deactivating the enzyme that forms ammonia. ClumpLock Technology locks in liquid and odor on contact to form tight clumps and make scooping easy. Certain trademarks used under license from Procter & Gamble Company or its affiliates.
