Private sleuth Sun Jinrong brought heat detectors, a lens that fits inside small spaces and a blowdart loaded with a tranquiliser to search for a desperate client's missing loved one in Beijing: A cat named Duoduo.

Unlike Jim Carrey's goofy Ace Ventura character, the man dubbed by China's media as the nation's first pet detective is a stoney-faced animal lover who solves cases with the help of high-tech gear worth thousands of dollars.
Sun has reunited 1,000 missing pets with their owners since he launched his business seven years ago.
