Nature Cat, a WTTW/PBS Kids series you can watch on WTTW11 and wttw.com/kids, is about a house cat who dreams of exploring the great outdoors. In each episode, once his family leaves for the day, Fred transforms into a “backyard explorer extraordinaire.” Nature Cat can't wait to get outside for a day of backyard nature excursions and bravery, but there's one problem: he's still a house cat with no instincts for nature. Don’t miss this chance to meet and greet this fun and friendly walkaround character.
