Mysteriously, a second FN arrived here a few days after my first one. I waited, ready to send it back in case two were mistakenly shipped, but heard nothing, and my boyfriend (who did the actual ordering) wasn't charged and only had any information for one cage. I'm trying to figure out who got it for me, but whoever my secret admirer is must wish to remain secret ^^;;
But anyway, I gave the big girls the entire two level back, and set up one half of the new one for the little girls. I also added the bottom shelf from the first cage, so it's twice as high (to discourage possible escaping), and since I'm not using the second level, I added the second shelf to the cage.
Since I wasn't expecting to keep this cage I don't have much to put in it. I'll probably take some stuff out of the big cage. The older girls still almost never go into the bottom half. I might put the food and wheel down there at some point. My 11" Wodent Wheel for the little girls' cage should get here soon too ^_^
