In creating Catit Go Natural Pea Husk Clumping Cat Litter, we use pea husks that would otherwise be discarded. The pea fibers are mixed with raw, food-grade materials such as starch, corn powder, and guar gum, which act as natural clumping agents. The result are soft, cylindrical litter pellets that clump without sticking to the litter box, and feel nice to your cat’s sensitive paws.
