An exclusive cat litter formula made from the fibrous material of the walnut shell, Naturally Fresh neutralizes litter box odors better than clay, pine, corn, and wheat litters. One bag of Naturally Fresh is equal to three bags of the leading clay litter. Our super-absorbent formula produces tight clumps in as little as 15 minutes, making cleanup easy and mess-free. Unlike clay litters, Naturally Fresh contains no silica dust so you and your cat kid can breathe easy. It also doesn’t stick to your cat’s paws, so litter won’t be tracked through your home.
