Extra Strong Clumping Unscented Cat Litter has an increased clumping ability and actively works against crumbling to instead generate large lumps that are easy to remove from the litter box. The soft sand is completely fragrance-free to appear natural for sensitive cats. 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. Scent-free so as not to cause allergies to sensitive cats.
