Faster clumping means easier scooping. Made from 100% natural walnut shell, Naturally Fresh Quick-Clumping Cat Litter produces tight clumps in as little as 15 minutes and doesn't stick to the litter box. This super-absorbent formula works best for pet parents of one or two cats and provides superior odor control, absorbs three times better than clay litter, and is virtually dust-free. Plus, Naturally Fresh is toxin-free and 100% biodegradable, which means it's safe for you, your cat kid, and the environment.
