Yep, it's just the kitchen which is attached to a 2x4 C&C cage with a 1x2 loft. This just contains the hay and much of the mess! It puts the pet store cage to good use and frees up space in the C&C cage.
I have that same cage and not to make anyone mad, I am currently using it as a cage. I had to take down my 2x2 c&c due to size issues. It will be going back up soon though.
