When P-22 – the puma that lived in LA's Griffith Park – died in December, Angelenos mourned the loss of one of their wildest celebrities. In his new book, Open Throat, Henry Hoke pays homage to the late cat in a different way; he takes on the voice of a mountain lion living beneath the Hollywood sign, pondering community and climate change and gender identity. In today's episode, Hoke speaks with NPR's Scott Simon about what P-22 represented for Los Angeles residents, and why writing from his perspective raises so many questions about our own humanity and isolation.
