Haha yeah.. I didn't have enough time to properly explain.I'm not sure if I totally understood. Once you've built the rectangle, then you've got 2 cages that need to have a safe passage. I have 2 cages that I connected by getting a heavy duty plastic pipe thingamajig from Home Depot and snipped the wires of the cages a little smaller than the pipe/ tube and stuck it in. The part of the cage that you cut can double as a bit of support for the tube. It was easy. Don't know if that helps.
