The CDFW defines a mountain lion attack as an incident resulting in direct physical contact between a human and a mountain lion resulting in physical injury or death to the person. An attack is verified only when a physician, law enforcement officer or CDFW personnel determine the injuries were caused by a mountain lion. Incidents reported as attacks that do not fit the criteria of verifiable attacks on humans are not included in the list below.
