Our verdict
Pick Dr. Elsey's Ultra for hard clumps and very low dust from bentonite clay. Pick World's Best Multiple Cat for a lightweight, natural corn litter.
The central trade-off
Material. Bentonite clay versus whole-kernel corn.
Weight. Corn is lighter to carry.
Both. Unscented and clumping, so both suit boxes that take clumping litter.
