difficult to assemble alone but got it done, one side panel the instructions do not caution about its orientation and  I believe it's in place upside down. manufacturer should check that out and place a warning. I'm going to see it my bird can figure out how to open the feed doors before I go for a reassembly. perches also are oversized, only the small one for the play area is right length. other than that was a fun project to assemble, waiting for additional perches before I place my feathered buddy in it, 2 perches??? for that size????
