Still no upgrade, sadly, but the 2x3.5 is better than their pet store cage! I "remodeled" the cage a bit, though I still don't have the hay rack exactly where I want it.

If there are any suggestions on my setup, please let me know! I really want to make it nice for them, though I am hopefully upgrading to a 2x5 very soon.
