A 65-year-old Californian woman has saved the life of her husband, 70, by fighting off an attacking mountain lion with a small log and his pen.
Jim and Nell Hamm were walking in the Prairie Creek Redwoods State Park when the cougar wrestled Jim to the ground.
Nell started hitting the animal with the log but it kept hold of Jim's head. She then tried to stick the pen in its eye. The cougar eventually let go.
Mr Hamm is in fair condition after having his lips stitched back together.
He also suffered scalp lacerations and puncture wounds.
