Category: Pets > Cat litter. Updated 2026-10-08. Based on 341 counted first-hand reports from Target shopper reviews, Feb 2019 to Oct 2026.

**Question:** Which cat litter forms solid clumps that scoop out clean?

**Short answer:** Arm & Hammer Slide Easy Clean-Up Litter has the best record for clumping: 34 of 35 owners said it formed firm clumps that lifted out in one piece. Fresh Step Odor Shield Multi-Cat Litter follows at 30 of 37, and World's Best Clumping Formula does about as well (20 of 24) from a smaller group. Tidy Cats Instant Action Clumping Litter has the weakest record here at 11 of 22.

**What stands out:** Brand isn't a shortcut. The two Arm & Hammer litters sit far apart (34 of 35 for Slide Easy, 20 of 35 for Clump & Seal), and both Tidy Cats litters land in the lower half.
