PH>In another part of my life, I'm a volunteer firefighter and former
PH>paramedic. Lexan is used to make the helmets and face shields we
PH>wear. It does take a lot to scratch the lexan face shield...and I doubt
PH>a parrot, even a macaw, could bite through that stuff. It's much harder
PH>than plexiglass and much stronger and lighter than fiberglass of the
PH>same thickness.
And I bet it costs almost as much for a Lexan cage as it does for the
macaw to put INTO it!!!
