Better than I ever thought it could be
Honestly this cat box has changed both my cat’s and my family’s life. Our old boy has arthritis and struggled to use the regular cat box in let’s say, a clean way. There were always tracks leading from the box and cat litter scattered all through the ... Show More![]()

Oh So Quiet!
The Litter Robot 4 is so quiet, you don't hear it at all. It's predecessor was quiet , but not this quiet! I'm still however trying to coax my "shy" cat into using it. I think most cats have no problems at all, but my Tutti is very timid and everyth ... Show More![]()

If you’re in doubt, don’t be. It’s so worth!
I just got two cats and knew I wanted to get an automatic litter box since my friends all recommended it. I went from one small litter box to this and it’s been so helpful. I would need to scoop 2-3 a day and it sucked to have to wake up early and st ... Show More![]()

This depends on the type of litter you're using. For example, with the recommended standard-weight clay-clumping litter, approximately 17 pounds of litter is used when added to both the Litter-Robot 4 globe (just below the MAX fill line) and the LitterHopper.
