Oh Gal loves the cage! At first I don't even think she knew she was in one!

I plan on adding more perches, she loves them, and I think the more the better for her species since they are naturally canopy dwellers and poor flyers.
As for Jovie's cage...
I think you're right, it's right around 20 x something, but like I said I have misplaced my measuring tape because I am scatter-brained. The boing is a brilliant idea! So far I have a few ideas of how to modity it. I plan on getting an unfinshed plank of pine as per asuz's suggestion, and attach it so that it grants her access to her food and water dishes. I saw some fleece-lined sleeping tents that look perfect for a bird with her disability. And the boing would be great too, with some flat perches throughout the cage so she has places to rest. And maybe wooden ramps to grant easier access to different levels of the cage.
I need to get this done fast, she can hardly do much at all in her current cage. She plays with her toys and climbs around, but for the most part she just hangs there on one of the four tiny panels of bars in the cage all day long.

Her poor feet never get a break! I haven't seen her use the single perch she has at all yet. She looks absolutely miserable. I want to get her out, but know I should wait a couple more days so she can be used to my presence. Poor Jovie.
