P-22, the famed "Hollywood Cougar," was born in a national park near Los Angeles, California. When it was time for him to leave home and stake a claim to his own territory, he embarked on a perilous journey--somehow crossing sixteen lanes of the world's worst traffic--to make his home in LA's Griffith Park, overlooking the famed Hollywood sign. But Griffith Park is a tiny territory for a mountain lion, and P-22's life has been filled with struggles.

Residents of Los Angeles have embraced this brave cougar as their own and, along with the scientists monitoring P-22, raised money to build a wildlife bridge across Highway 101 to help cougars and other wildlife safely expand their territories and build new homes--ensuring their survival for years to come.
