BBC: P-22, Hollywood's celebrity mountain lion, ends his reign

On Saturday, the hearts of P-22's fans were shattered when the California Department of Fish and Wildlife announced that, due to his old age and a host of serious heath issues, the legendary feline was humanely put to sleep. Officials called it "the most difficult, but compassionate choice."

He has had the city in his thrall since 2012, when he somehow managed to get across two deadly freeways and take up residence in Griffith Park, a 4,200-acre mountain in the heart of one of the world's biggest concrete jungles.

Since then, his charisma and curious choice of city habitat have made him a local folk hero. His plight - trapped in an urban island with no possibility of finding a mate - also made him the face of a movement to protect the threatened species.

Though he will no longer prowl through the heart of Los Angeles, his decade-long reign has cemented his status as a Hollywood star as bright as any on the big screen.
