The cage is built with good enough quality, but after using it for two weeks, we are really unhappy with it. The hamsters have moved most of the stuffing into the wheel. They poop in there and everything, and then try to use the wheel sending poop, food, and stuffing everywhere! IT IS SO MESSY! Our kids can't even get our hamsters to come out of the wheel to even hold or play with them. DON'T BUY THIS CAGE! I wish I would have looked on amazon before purchasing this cage.
