A 7-year-old boy hiking with his family was attacked Saturday by a mountain lion... The boy, whose name was not released, was apparently in a group taking a short hike at a scenic area of Flagstaff Mountain, Division of Wildlife spokesman Tyler Baskfield said. "The father turned and saw the cat had a hold of the young boy," ... The group began screaming at the cat and throwing rocks and was able to free the boy... the mountain is prime habitat for the cats, and there had been several recent sightings of mountain lions in west Boulder.
