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.
When you have three or more cats, you need a litter built for volume — Scoop Away Multi-Cat is the only pick on this list explicitly designed and tested for that scenario, and it delivers on odor control where generic litters fall short.
