The state of OK was very protective of their cougars, despite that numerous attacks on livestock. After farmers raised hades with the legislature, the law was changed to allow the shooting of cougars that are a threat to livestock or humans. You are supposed to notify a game warden when a cougar is shot.

Couple of years ago i was tracking a wounded hog down an erosion gully when the hair on my neck literally stood up. Turned and there was a big male cougar sitting on the bank about 10-15 yards away switching his tail and licking his face; looking at me like i was lunch. The cougar took a 240 grain XTP from my .50 muzzleloader in the chest.
