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.
Reddit's pet communities consistently recommend World's Best above almost every other natural litter, with multiple owners in multi-cat homes saying their guests can't even tell a litter box is nearby. If you can stomach the price, it's the best non-clay option for multiple cats.
