I will try again this week to remove it because like I said above and you just stated, it definitely is too small. I just don't want to stress them out more right now. They've been quite skiddish since arrival, which I was told is unlike them so I'll be letting them calm down for a couple days other than giving the occasional treats. So far they only use the wheel to hide under and climb on top of.
