Leopards are hard on professional hunters. I've probably met half a dozen PHs who were grabbed by a wounded leopard while following it up. Chui can conceal himself where you would never think it possible and will land on you in a single leap before you can bring your gun to bear. Despite this, I don't know of any PH who was killed by a leopard. This is because, like all of the big cats, they learn how to kill from Momma, and if Mom has never taught them how to deal with a human, they're at a loss for what to do. In the days before antibiotics, a leopard mauling was often fatal, not because of what the cat did, but from the infection that inevitably followed.
