I currently have hanging cages but I would like to attach the cages to the wall. I saw a setup in which a type of hanger was used and the cages were simply lifted off and away from the wall. The hangers looked like they were pre-fabricated but I can't seem to find them anywhere. If you have your cages attached to the wall, what are you using? If you are using standard hooks, do you have any problems with the cage wire bending? Any and all suggestions are greatly appreciated.
