aha, what a smart baby you have on your hands, and spoiled he is l as for placement of toys with your dome top cage, provided that it does open, you may want to place a hook in the ceiling and hang an swing with toys hanging from it, or even a large rope ladder, like what I have in my living room, I have three hooks in the ceiling in different locations, generally where I place the cages right under them, hence plenty of toys and play time. Great story!
