Vegcast 79 looks at animal sentience, with an in depth interview with Jonathan Balcombe, author of the book Second Nature, which comes out today. Jonathan talks about how we are heading for a paradigm shift in thinking about animal intelligence, emotion and sensation, and explains how this will likely affect our food and other choices. Then we get to hear a new tune from Yvonne Smith, the Traveling and now Singing Vegetarian. We also check in with Leila Fusfeld to get the outcome of the Vegan Pledge campaign just completed in Philly. And in keeping with the theme there is a Science Fact about dog growls and how those that same to us mean different things to dogs.
