I have a hamster cage with a whole bunch of Accessories that you could build quite a good amount of adventure for a hamster or gerbil or mice. asking $30 for all of it. I’m not quite sure how it all goes together, but I’m sure somebody can figure it out. The bottom part of the cage doesn’t quite attach super firmly with the top part. I’m not really sure how it works, but somebody should be able to figure it out. Text me if you’re interested. I also have a second cage that definitely goes together really well that I am willing to throw in with this one. You can even attach them with the tubes and have a huge habitat for a hamster, gerbil or mouse.
