The search is on for Los Angeles' most famous wild cat.
Wildlife officials have said they plan to capture the mountain lion P-22 after concerns arose over possible "signs of distress" including killing a leashed Chihuahua last month and attacking another Chihuahua last week.
Although the prospect of finding and capturing an animal wearing a tracking collar may seem simple, a wildlife expert familiar with previous efforts to track and trap mountain lions told the Los Angeles Times on Friday that such operations are unpredictably complex.
