A six year old boy on vacation in Texas was suddenly, inexplicably, attacked by a mountain lion. It didn't even happen in the wild. It happened on the sidewalk right next to the lodge where the family was staying! The boy who survived the attack but sustained horrific wounds says the big cat just sneaked up on them. With his son's face locked in the jaws of the mountain lion, the father reached for a pocket knife and went after the animal. What happened next? Take a look at this video from CNN where the father tells the story. Warning: the boy who sustained some pretty bad injuries is shown in this video.
