A famed mountain lion who became a Los Angeles celebrity after living in the shadow of the Hollywood Hills for over a decade was euthanized on Saturday because of severe health problems, California officials announced.

The ageing mountain lion, called P-22 and thought to be about 12 years old, was captured in a Los Feliz backyard on Dec. 12 amid fears he had been struck by a car and was suffering other health problems.

The cat, who had traversed busy highways to take up residence in and around Los Angeles’ Griffith Park, became a symbol of campaigns to save California’s threatened mountain lion population. He was put to sleep at 9 am on Saturday at San Diego Zoo Safari Park, officials at the California Department of Fish and Wildlife (CDFW) said.

Tests on P-22 revealed “significant trauma to the mountain lion’s head, right eye and internal organs, confirming the suspicion of recent injury, such as a vehicle strike,” officials said.

The examination also uncovered irreversible kidney disease, chronic weight loss, extensive parasitic skin infection over his entire body and localized arthritis, officials said.

“Based on these factors, compassionate euthanasia under general anesthesia was unanimously recommended by the medical team at San Diego Zoo Safari Park,” the CDFW said.

Officials said P-22’s demise was caused by habitat loss and fragmentation, and called for the construction of more wildlife crossings in urban areas and well-planned spaces for them to roam.

“Mountain lion P-22 has had an extraordinary life and captured the hearts of the people of Los Angeles and beyond. The most difficult, but compassionate choice was to respectfully minimize his suffering and stress by humanely ending his journey,” the CDFW said in a statement.
