My granite corn, Edvard aka "Eddie" is by far the most voracious (and fastest) feeder in my collection... he's not even two years old yet, and already the size of any full-grown male corn. I swear, he would eat a dead cat if I offered!
I took some video of him eating tonight, number 2 of 3 f/t hopper mice he devoured in minutes. Make sure to watch or fast-forward to the end, because that's the funniest part.
