As the author of the video said, neither loud screams nor hand gestures frightened the big cat away, but heavy metal did the trick.
“I was out hiking when I noticed this cougar stalking me. it wasn’t afraid at all just kept staring at me. I started to play Metallica “don’t tread on me” on my iTunes and that’s how I finally scared it off!” she wrote in the description of the video.
Cougars can run 80 km/hour (50 mph) and have been known to attack people. "I definitely think Metallica saved the day there, for sure," she said.
