A mountain lion attacked and wounded an 11-year-old girl outside her family's home in Malibu, California, then chased her mother before it was scared off, authorities said Monday. The girl was near a chicken coop on the property Sunday evening when the cougar attacked her from behind, biting her arm, leg and lower back, according to California Department of Fish and Wildlife spokesperson Peter Tira. The young victim was treated at a hospital for minor injuries, Tira said.
