Yeah, Bull Snakes are non-venomous, but from what we have been told, they have a mouth like a sewer which can make you very sick if you are bitten; but usually they strangle their prey, like one of those Florida Pythons, - mucho bacteria and toxins - but a neighbor swears it was just a very large garter snake, who do bite when agitated, so maybe it was a garter (no rattles on the tail, so I'm pretty sure it wasn't a rattler, which are pretty common in our neck of the woods) ..... whatever it was, it's bite didn't take long to kill the roo!
