What's the best clumping cat litter for easy clean up? One that doesn't stick! ARM & HAMMER Slide Clumping Cat Litter has a non-stick formula that allows you to cleanly lift rock-hard clumps right out of the litter box—no scraping, no scrubbing, no elbow grease. That's the beauty of clumping litter versus non-clumping litter, which absorbs moisture but often means more frequent full box changes. If you're looking for the best cat litter for odor control, Slide brings the muscle with triple-action freshness that absorbs, locks in, and eliminates odors 24/7. Plus, it's backed by a 14-day odor control guarantee. The 99.9% dust-free formula helps cut down on tracking for a clean home. It's built with multi-cat strength and a light, fresh scent to stand heavy use without overpowering your space.
