It comes with all the parts for $159. So, December probably sometime. Right now, my hamster cage is 2 "side by side." I might put more burrowing at the bottom if possible. I took one wheel out, and the hamster started going into the other cage more, which has "toys" or "furniture." It would be cool to get another one of these frames and connect them. If this hamster dies, I shouldn't get a new one for now but could if I was settled into another home.
