Top Odor-Control Cat Litters of 2026

A strong odor in the litter box can quickly become a nuisance for both cat and owner. Choosing a litter that keeps the box fresh is essential.

What Makes a Good Odor-Control Litter

The best options pair a high-clumping mineral such as bentonite clay or a natural substrate like walnut shell or tofu with an active odor-neutralizing ingredient, usually activated carbon or baking soda. These ingredients adsorb ammonia and hydrogen sulfide, the two compounds that cause litter box smell, instead of merely masking the odor with fragrance.
