My 9 month old male kitten shares an enclosed litter box on the first floor with our other cat.  So, I was convinced that he would LOVE this.  [ I sure do, how COOL looking is it? . . amazing].  It has been set up for 2 days so far (with his own lightly used litter inside).  He's been inside a handful of times, but hasn't used it yet.  I'm going to wait a few weeks and see if he warms up to it.  Thanks Wayfair for offering such different, unusual items for humans and animals!
