This is my review for ScoopFree® Classic Self-Cleaning Litter Box.  My cat has never had the experience of using this type of litter box before so I was very curious to see how he did with it.  It took a few minutes to get it all put together but once set up and plugged in I let him check it out.  He wasn't impressed with the part that moves but after it being still for awhile, and finally having no choice but to use it, he did so.   Not sure he loved it but he did use it.  It seems to be very good quality so I hope it works out long term.
