This thing is amazing!! I absolutely love the PetSafe Scoopfree self cleaning litter box!! Really wish I had this years ago!! It’s really made my life easy and my house smell better! It was very easy to put together and the directions were easy to read. I was worried that my two cats might get scared of it but they didn’t. I kept the old traditional box out for a couple days just in case they wouldn’t use it but they did. They used it right away and then when it starts cleaning they enjoy watching it. All I have to do now is raise the end cap piece and scoop their stuff away after the box did the hard part of collecting it all. Best invention ever!!
