For most homes, the best odor control comes from a hard-clumping baking-soda litter like Arm & Hammer Clump & Seal Platinum, with Dr. Elsey’s Ultra the top pick if you prefer unscented and the hardest clumps. Corn-based World’s Best is the natural/flushable choice. The rule across all of them: hard clumps that do not break apart beat any added fragrance.

How we evaluated odor control
We looked at four things that decide whether a box smells: clumping strength (hard clumps trap and remove urine whole), inherent odor neutralizing (baking soda and activated formulas), dust (which carries odor and is worse in small spaces), and tracking. A litter can smell "fresh" in the bag and still fail if its clumps crumble — so clump integrity mattered most.
The picks
Best overall odor control: Arm & Hammer Clump & Seal Platinum. Baking soda plus a tight-sealing clump gives the longest real-world odor control, especially in multi-cat homes.
Best unscented / hardest clumps: Dr. Elsey’s Ultra. If you or your cat dislike scent, this is the one — rock-hard clumps, 99% dust-free, and it works in sifting/mechanical boxes.
Best natural / flushable: World’s Best. Corn-based, lightweight, and clumps well for a plant litter — the pick if you want to avoid clay.

Even the best litter needs daily scooping and the right number of boxes. For the full routine, see our guide to eliminating litter box smell, and if you are in a tight space, the small-apartment playbook.
Want to automate the scooping? A self-cleaning box keeps odor down between changes — see the best automatic litter boxes. And to stop tracked litter (and the smell that rides along with it), the best litter mats finish the setup.

Odor-control litter: FAQ
What cat litter is best for odor control?
A hard-clumping baking-soda litter such as Arm & Hammer Clump & Seal Platinum for most homes, or Dr. Elsey’s Ultra if you want unscented with the hardest clumps. Clump integrity matters more than added fragrance.
Is scented or unscented litter better for smell?
Unscented with strong clumping usually wins. Heavy fragrance can mask odor briefly but many cats dislike it, and it does nothing about the waste itself. Baking-soda neutralizers are a better odor tool than perfume.
Does clumping litter control odor better?
Yes — hard clumps let you remove urine and feces whole every day, which is the main driver of odor. Litter that crumbles leaves waste behind and smells faster.
How can I make any litter control odor better?
Add a baking-soda litter deodorizer, scoop daily, and keep enough boxes. These work with any litter you already like.
