P-22 Day Festival: Ever been at a party where the guest of honor was running late? Or maybe didn’t show at all? First things first: P-22, the much mooned-over mountain lion that many of us flat-out adore, will not be at his big bash. But those who love urban-dwelling critters, like the sizable cats that roam our hills, will be there, all to learn how we can live alongside the animals of Los Angeles. A virtual reality cinema and 100+ exhibits will round out the free to-do, which is part of Urban Wildlife Week. Oct. 19 is the purr-fect date for this feline fun.
