Now to some wildlife in our own backyard: Bobcats.

These wild felines can be found all over Southern California but over the last decades researchers have noticed a disturbing trend. More and more bobcats seem to be dying from mange, a parasitic skin infection that's usually seen in dogs.

Joanne Moriarty, an ecologist with the National Park Service out in Thousand Oaks, joins the show with more. She's been part of the longest-running study on bobcats ever conducted.
