Why upgrade to Litter‑Robot?
The problem with a traditional litter box isn’t just this unpleasant chore. It’s also the foul odors, messy litter tracking, territorial issues in a multi-cat home, and more. With Litter-Robot, self-cleaning technology automatically removes the waste for you. You only need to empty the waste drawer when it’s full.
