If you won't believe a snake will eat a golf ball, would you believe they will porcelain door knobs? I've seen my grandmother more than one time cut one out of a rat snake. That's what she used in the nest. But of course that was some 60 years ago and those were old chickens and old snakes. Bless their soul, the old timers didn't know any better. These modern know it alls have more technology to prove their point.
