Very special episode for a very special cat. The day after the legendary Los Angeles mountain lion P-22 took his last breath, we talked with Natural History Museum wildlife biologist Miguel Ordeñana about his decade-long study of P-22 after discovering him in Griffith Park. Beth Pratt of #SaveLACougars and the National Wildlife Federation also shares how P-22 fueled her passion for saving this species from extinction — and we hear what one animal meant to millions of Angelenos. Learn all about how a cougar got into a city park, how he survived the journey from home, what he ate, how he captivated the world and how he changed the way  we see urban wildlife. Also: the circumstances that led to his death this week, and the legacy he leaves. This one means a lot to us, so share it if you can. Visit Beth Pratt’s website and follow her on Instagram and TwitterFollow P-22 on InstagramFollow Miguel Ordeñana on InstagramA donation went to the National Wildlife Federation #SaveLACougarsMore episode sources and linksOther episodes you may enjoy: Felinology (CATS), Procyonology (RACCOONS), Raccoonology (PROCYANIDS), Cervidology (DEER), Field Trip: How to Change Your Life Via the Natural History Museum, Aperiology (MACRO PHOTOGRAPHY)Sponsors of OlogiesTranscripts and bleeped episodesSmologies (short, classroom-safe) episodesBecome a patron of Ologies for as little as a buck a monthOlogiesMerch.com has hats, shirts, masks, totes!Follow @Ologies on Twitter and InstagramFollow @AlieWard on Twitter and InstagramEditing by Mercedes Maitland of Maitland Audio Productions and Jarrett Sleeper of MindJam MediaTranscripts by Emily White of The WordaryWebsite by Kelly R.
