Virtually Dust-Free and Low Tracking - Unlike clay litters, our eco-friendly litter contains no harmful silica dust – so you and your pet children can breathe easy. Soft on paws, it’s also cat litter that doesn’t stick to paws, so it won’t be tracked through your home. And because our pellet litter is non-clumping, biodegradable, and compostable, cleanup is especially easy.
