Recently, I had a thought. The Mary, at 80 by 50 centimetres, is larger than the zoozone the boys are in (72 by 46 centimetres). While it's not much difference in size, I figured it was a big difference when you're only a couple of centimetres long!
I had two worries. One was access -- while the zoozone has a large top door, the Mary has one small side door and one larger top door. The other was the bar spacing. However, I know many people who have successfully kept Roborovskis in cages with one centimetre bar spacing before, and tested it out with Rocco. He could not fit through the bars, and I decided more space for the hams beat any access concerns I had, so today I swapped them over.
I've tried to leave the layout as similar as possible to the one from the zoozone, although I did swap their wheels to eight inch wooden wheels rather than the flying saucers they had. Winter had started doing impressions of the Amazing Flying Robo off the saucers, which was concerning me. The eight inch wheels are larger than necessary, but there's more space for them to run together in an eight inch wheel than there is in a six inch one, the smaller size down in this particular wheel. (I coated them in plastikote, a waterproof child safe paint, so that they're easier to clean.)

As for the zoozone, well... Darla got it, so the last cage tour for him is out of date already, although I did try to keep the layout as similar as possible.
