Litterfree Paws is a lump-forming cat litter made from large grains that prevents sand from getting stuck in the cat's paws and spreading outside the box. The unique charcoal technology also allows urine and feces to bind quickly, leaving a fresher scent that seems inviting to your cat. Ever Clean cat litter is the first American lump-forming cat litter ever. This lump-forming cat litter has optimal absorbency, which means that the urine does not penetrate to the bottom of the box where bacteria are formed. All grains of cat litter also contain activated carbon, which helps to capture and neutralize the molecules that cause bad smells. This means that you get a fresher scent at home, while less time has to be spent cleaning the box. In addition, the sand is completely natural and allergy-friendly, which makes it gentle on your cat's paws. Captures and locks the odour instead of hiding the odour and eliminates urine, feces and ammonia odour on contact. Extreme clumping ability, which creates less odour and makes cleaning easier. Large-grained to avoid the cat getting sand outside the box.
