If you only try one litter, make it Dr. Elsey's. It's the rare product that experts and cat owners on Reddit agree on, unscented, hard-clumping, and works in automatic boxes too.
What holds up
Medium-size bentonite clay granules form hard, easy-to-scoop clumps
No added scent, vet-preferred and controls odor naturally
Compatible with self-cleaning litter boxes like the Litter-Robot
40-lb bag lasts up to two months with one cat at ~52¢/lb
What to know
40-pound bag is very heavy and awkward to pour
Initial pour can kick up dust before it settles
Pricier per pound than budget options like Special Kitty
Expert verdict
Daily litter-box cleaning became a 20-second chore with this litter. Because of its reliable clumping it's also among the best cat litters to use with self-cleaning litter boxes like the Litter-Robot.

I swear by world's best. It's expensive, but so freaking worth it. We have two cats and two litter boxes, one of which is under our big table in the living room. When my mom comes over, who has an EXTREMELY sensitive sense of smell, has no idea it's there.
If you're constantly sweeping litter off your floors, Tidy Feet is the fix. The larger granule design is a genuine engineering solution to tracking, and it earned the Good Housekeeping Seal in both scented and unscented versions.
What holds up
Larger, specially shaped granules resist sticking to cat paws
Low dust formula, better for cats and owners with sensitivities
Clay and activated charcoal combination aids odor control
Earned the Good Housekeeping Seal in both scented and unscented versions
What to know
Cats with very sensitive paws may resist the larger granule texture
Higher cost at ~77¢/lb compared to standard clay litters
Larger granules may not clump as tightly as fine-grain options
Expert verdict
The Tidy Cats brand has engineered larger, different shaped clay granules that don't easily stick in cat paws like smaller-grained litter. That means less tracking and less cleanup outside of the litter box.
I use the regular kind of Tidy Cats 24/7 performance litter (not the lightweight kind) and it works really well. Haven't had any serious problems with it. I have an LR4 and three cats.
Don't let the low price fool you, Special Kitty holds its own against litters twice the cost. If budget is your primary concern and you don't mind a quick sweep around the box, this is the smart buy.
What holds up
Lowest cost per pound (~48¢) of any recommended clumping litter
Easy-pour 14-lb jug with screw-top lid, no heavy bags
Unscented bentonite clay formula works for multi-cat households
Recyclable jug packaging
What to know
Tracks more than premium options, expect some litter outside the box
Clumps not quite as tight as Dr. Elsey's or Arm & Hammer
Only available at Walmart, not sold on Amazon or Chewy
Expert verdict
If you're looking to keep costs low, prefer a 14-pound jug to a bag or box weighing 20 pounds or more, and don't mind the occasional sweep around the litter box to pick up a few tracked granules, this Walmart exclusive has a low price and is easy to use.
