Introducing Litter-Robot 4

The litter box that'll change your life

How it Works

Having a cat is magical.
The ordinary litter box? Not so much.
Meet Litter-Robot 4.



Our automatic sifting process discreetly removes waste so you never have to scoop again.

Neutralizes odors

The tightly-sealed waste drawer and optional OdorTrap™ system eliminates stubborn litter box odors.

Real-time insights

OmniSense® detection tracks cat activity, litter levels, and waste drawer fullness.

Multi-cat friendly

Our MultiCat™ design provides a comfortable space for cats of all sizes, suitable for up to 4 cats.


The Whisker app lets you monitor usage, view stats, and receive custom alerts right from your phone.

Less tracking

Automatic sifting ensures a clean place for kitty’s paws, while the included fence catches kicked-up litter.
“So easy to set up and my kitty took to it right away. No smell at all. Love not having to clean litter all the time!”
- Leigh K.

How it Works

Compact size

Same footprint as a traditional large litter pan. No need to make space or elaborate installation plans.

Smooth transition

Many cats acclimate within a week. If only they could talk, they’d tell you how great it is.

Easy setup

Use any clumping cat litter and regular trash bag. Or add some of our custom accessories.

You and your cat
deserve a better
