I gather it worked?
What did the cougar do next?
Geez, the story says...
"Gibb said his yells, screams and kicks kept the cougar at bay until his brother called him back to Sasha, who had run toward a church. As soon as they got to a veterinary clinic nearby, they called RCMP, who notified Fish and Wildlife officers.
...
"Whitecourt RCMP Sgt. Tom Kalis said there’s a wooded area near the Tim Hortons, which is where police found the cougar in a crouched attack position. Fish and Wildlife officers arrived about an hour after the incident, he said, and the cougar was destroyed."
