Happy Birthday!!
Hey Gatordave, the cage is made from some plastic/pvc window material - I couldn't even tell you what it's called - I saw it in the store, got a few 8ft sections, and bended, twisted, cut, screwed together, and glued them together.... they were kinda like strips you would put between the window and wall or sill to fill a gap or something... if I find them I'll send you a link. Once the thing was put together, I mache'd it with newspaper and painted (black and red for rust)... hung with fishing wire and rope.
