Arm & Hammer Double Duty cat litter was my first try with the brand. The odor control is impressive, especially in warmer months. Clumping is decent, though not as tight as Clump & Seal. The scent is stronger, which didn’t bother me but might bother some cats. Mine adjusted fine. Combined with Kirkland Signature wet food, it handled moisture pretty well. I eventually switched formulas, but Double Duty held up during a busy foster period.
