Running from a big cat is not the thing to do, although it probably seemed like the thing to do at the time, but a running, fleaing, target actually triggers the attack for big cats. I have a friend here in CO. that arrowed a large tom(mtn. lion) a few years ago while elk hunting. He tried to slowly back away from the cat, but the cat kept stalking him, finally, when my friend felt that he was in serious danger, he arrowed the cat, and then left the area. Reported to the game department, and they went and recovered the cat. The DOW took the cat, but allowed me friend to buy it back from them later, before thier annual auction. Go figure!
