Ever Clean Extra Strength Clumping Litter free of added fragrances and perfumes, makes smelly litter boxes a thing of the past. This premium clumping cat litter is fortified with Ammonia Shieldand CarbonPlus technology, providing 14 days of odor control guaranteed for maximum odor protection. CarbonPlus grabs and eliminates odor from urine and feces with its activated carbon bonded to and mixed within the litter granules. While this super premium litter is fragrance free, the highly absorbent moisture lock creates extra strong clumps as soon as the litter comes into contact with liquid to prevent liquid waste from reaching the bottom of the litter box where it can decompose and create odors.
