Introducing Litter-Robot 4

The litter box that'll change your life

How it works

Stop scooping. Neutralize odours.
Upgrade to a smarter litter box.


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

Neutralizes odours

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

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.
