Don't ask me why, but I love Superpet's Habitat Defined range and spent a long time tracking down one of these 'avian enrichment homes' for my parrotlet. It's definitely the most unusual bird cage out there. I created this set-up a couple of weeks ago and Olive seems perfectly happy to reside in there when she's not out 'helping' me with fursuit work. It's more spacious inside than it looks from the front, as it's almost as deep as it is wide. I only attach the play-gym when she's out, as otherwise it reduces the space and light in the cage. The roof/lid itself is clear like the door, so I ran some rope-perches along the top so I can hang toys from them.
