Very sleek looking. Not too hard to put together but if you don’t screw the doors on just right, they will not close. I was able to add a stud at the bottom to hold the doors closed, because the doors have a little divot that seems to have been made just for that. 

I did not use the liner and it gives kitty loads of room and fits a Breeze litter box well. It doesn’t completely eliminate odour, given the opening for kitty to get in and out, but minimises it.
