We got our cage from a local guy who builds his own. He made it for sugar gliders, but it works just fine. Just don't get a cage with a plastic bottom. They will chew through it. Ours had a one inch hole half way around the side of our rat's cage, and they were only in it for a weekend (we were waiting for a cage to be ordered for us, but it was a plastic bottom cage, so we bought one the guy had made instead, even though it had a wire bottom. I'm just glad they proved they'd chew out before we spent $90 on the cage).
