Arm & Hammer Clump & Seal is the strongest all-around pick in this comparison for budget shoppers prioritizing odor control.
A budget-friendly clay litter with aggressive odor control and easy store availability, offset by strong fragrance and more tracking.
The best litter under $15 if you need simple clumping performance and broad availability more than premium dust control.
Super Scoop is the cheaper Arm & Hammer bag. Clump & Seal is the one with the long-lasting fragrance and the firmer clumps. If the box lives in a bedroom or a studio apartment, settle the fragrance question before you look at the price.
