WARNING - Zachery S. Warren suggested to ferret proof with hot glue and
window screen.  This is not a suitable ferret proofing material for some
ferrets.  Boum Boum destroyed the metallic screen of a screen that was
stored in a closet.  He is more persistent and destructive than our other
ferrets but I am convinced that if any that wants it can tear a screen.
