I have a 1 yr old female veiled Cham. I am having a cage built by a master craftsman. The problem he is running in to the the screen. He is using basic metal screen like what is used on ur windows. But having a problem every time he tryes to pull it tight and secure it, it breaks. He was thinking the only way might to be starting over and building it like a window frame( ie. the groove running all the way around the inside, and securing the screen with a rubber strip. Like a window screen). Does any one know of another material he can use for the sides of the cage?
