I was hesitant about the size at first, but after putting it together it actually fit quite nice. We use the Tidy Cats Breeze litter system and it fit perfectly. The little steps give it that cute charm. It did take a while to put together because of all of the little pieces. But it was worth it. The kitties took to it quite well too. I definitely recommend this for anyone who is looking for a cute litter box hideaway. Or even just a kitty playhouse.
