$20-$40
Summary
Baking soda formula tackles odors aggressively and comes in a convenient cardboard box that's easier to pour and store than most competitors. A solid mid-range pick.
If you're using a self-cleaning box like the Litter-Robot 4, clumping clay or bentonite litter is essential for the mechanism to work properly. Pairing the right litter with the right box is half the battle.
Pros
- Cardboard box with plastic handle is easier to pour and store than bags
- Baking soda formula provides strong scent neutralization
- Widely available in grocery and big-box stores
- Competitive price point for clay litter
- Clumping clay and bentonite litters work seamlessly with automatic box mechanisms
- Reduces how often you need to interact with waste
- Spacious Litter-Robot 4 globe accommodates most litter types
- App connectivity lets you monitor litter levels and usage
Cons
- Clumps are softer and more prone to breaking than Dr. Elsey's Ultra
- Scented formula may irritate sensitive cats or owners
- Higher dust output compared to Dr. Elsey's and World's Best in testing
- Litter-Robot 4 itself costs $500+, making this a premium setup
- Some litter types (tofu, long-grain) not recommended for automatic boxes
- Ongoing litter cost adds up on top of device investment
Our take
Arm & Hammer Super Scoop is the practical everyday choice — it's widely available, affordable, and the box design alone makes it less of a chore to deal with. Clumps aren't as rock-solid as Dr. Elsey's, but for most single-cat homes it's more than enough.
The Litter-Robot 4 is the best automatic litter box on the market, and it only works well with quality clumping litter — don't cheap out here or you'll be cleaning the globe constantly.
