Here is the two story cage, with the top open. It attaches to a latch on the wall to hold it open
Here is a detail of the latch
A side view of the cage -- it is angled in the back to fit the a-frame of our house.
There is a door on the bottom story that can be dropped down and let the bunnies come in and out.
...here it is open
The bottom is on a rail that can be pulled out for cleaning.
A top view -- shwing the later to upstairs
Another side view. The bottom left area also has a door for easy cleaning of the downstairs.

Happy bunny.
