One of my most hated household chore is cleaning the litter box. My mom love to have her cats around, and frankly, I do not. When I heard about this ScoopFree Self-Cleaning Litter Box, I was stoked. I couldn't have asked Santa for a better gift. This litter box is easy to set up and comes with crystal litter. It does need to be plugged in so make sure to have it near an outlet. I was surprised at how quiet this operates. I expected something like R2D2 to come out, it doesn't wake me up in the middle of the night and it doesn't scare the bejesus out of the kittens. I am thrilled and would recommend!
