LindoCat Crystal Aloe Vera is a hygienic litter comprised of fine crystals of silica gel, a hypoallergenic material which is harmless to cats and is outstanding for its absorption of liquids and odors. LindoCat Crystal Aloe Vera dries solid waste, thus facilitating its removal. The crystals quickly trap and retain urine, blocking the growth of bacteria and unpleasant odors, while releasing a pleasant scent of aloe vera. LindoCat Crystal Aloe Vera is light-weight to carry, does not develop dust and does not stick to cats' paws.
