Editor's note: The OP's post is very misleading as was the USA Today article. The animal in question appears to still have been a juvenile mountain lion that likely weight 35-40 pounds at the time of the attack.
Rapidly deflating erection's note: The OP is also a dickhead for implying that the guy who killed the cat was himself bragging about it. People who are operating on a few more intellectual cylinders than this remember that is was OTHER PEOPLE who didn't know squat about the details who were calling this guy the Chuck Norris of the ultra world. Morons put him on a pedestal, and when the full story emerged, the same morons acted as though he'd vaulted up there himself.
I wish far more runners, in particular males 18 to 25 years old, would be eaten by mountain lions. I wish it were as common as having a bird take a dump on your car.
