This is a beautiful way of hiding a litter box! I have 2 cats and neither had any issues with adapting (and one is about 15 years old). I got the large and it was plenty big to fit my litter box that I was previously using. Easy to put together- hardest part was adjusting the doors to close right. Drawer in the top is convenient for keeping bags and the litter scooper. Very happy with my purchase - it looks great and hides the smells. The litter catch is also a must-have addition.
