I was thinking of building a new cage. I am not sure if I wanted to use wood or aluminum. What are the good points and bad to each? I have aluminum right now. I tried to build a larger aluminum one but I need to redo it or make a new one. It was my first try and it just seems to bend to easy. I didn't get the screen tight enough either. I know some people like the aluminum and some like wood. Can you anyone give me any suggestions and cage designs?
