Yep! It's the double Critter Nation without the divider between the top and bottom.
Most of the bird cages I looked into that were as big as I wanted either had inappropriately wide bar spacing or seemed to be kind of flimsy with small doors. This one has half inch bar spacing, is heavy duty, has huge doors, and doesn't have those little sliding doors he can get out of (in his old cage I secured them with pear links, but he figured out how to unscrew those, so I started using those plastic chain links and just hoping he wouldn't pull them hard enough at the right angle to take them off).
