I was skeptical about this product b/c of the reviews, however I really love it! I got the black jumbo and it looks great! There was no warping of wood and it fits my large litter pan. The cats had no issues adjusting to it. It also keeps my dog out!  The only thing they could improve on is a slide out rack the plastic tray could fit in and the doors are a pain to adjust. However they do give you hints how to align them and one done, they look great! Excellent product for the price!
