This self-cleaning ScoopFree litterbox is amazing in every way. My cat was a bit lost and curious at first,trying to check it out and see what it was. Once she realized it wasn't going to come at her, she used it and then watched it clean the box and move back & forth. Both my cat and I was amazed. The clear crystals are nice and the litter container is great to easy dispose of. It can be abit expensive  to buy the pans but its still worth it.
