Summary
Tens of thousands of five-star Amazon reviews and a baking soda formula that locks odors for days — the best budget-friendly pick for multi-cat homes that need serious odor control. Tested by Good Housekeeping with two senior cats and passed the smell test even after days unscooped.
The go-to unscented clay litter for multi-cat homes. Medium bentonite granules form rock-hard clumps that make scooping a 20-second chore, and vets prefer the fragrance-free formula.

Our take
For the price, Arm & Hammer Clump & Seal punches above its weight on odor control — it's the litter Reddit and Good Housekeeping both recommend when you need something affordable that actually works in a busy multi-cat household. Just know the quality has reportedly slipped recently, so buy fresh.
If you have multiple cats and want one litter that just works without drama, Dr. Elsey's is it. It's the rare litter that experts and Reddit both agree on, and it's compatible with self-cleaning boxes like the Litter-Robot.
