Example, do I stack 3 (54in) or 4 (72in) of the 30x18x18 cages.
I'm thinking that the top cage may have to be a "look but don't work" cage, as the access would be difficult. Example, to look in the nest of the top cage, I would need a ladder.

For those of you with stacked cages (Tiffany, Candice, etc) how does the top cage work? Is is visible, how do you work it, etc.
Thanks
