here is a pic of my cage. these bg were not put in the cage. i throw a little food in there daily and the bg just start hanging out. i can't remember how many months it took to grow them this size, but it wasn't very long. the square pvc piece is my feeder ring. it keeps the feed from floating out of the cage. i bought 3/4" plastic mesh and some special pvc fittings.
