This non-clumping formula is made to control up to 7X more ammonia-causing odors than leading non-clumping litters. Made from a blend of walnut shells, this eco-friendly litter may help neutralize odor better than clay, pine and wheat litters. Formulated with annually renewable sources and no chemicals, toxins, clay, corn, or grains, so it's safe for you and your kitten. Virtually dust-free means you can breathe easier in your home, and makes this litter safe for pets or owners with respiratory problems. A low-tracking material ensures your furry friend won't be tracking litter and bacteria throughout your home.
