In this episode, we ask: how do cats detect earthquakes? How do owls hunt in total darkness? How do cheetahs accelerate more quickly than a supercar? How do sea otters keep warm in icy waters? And, how do ants heal their wounded?

Are dolphins as smart as we think they are? How do hyenas eat everything last scrap of their dinner? How do geckos defy gravity? How do leeches suck blood? And, why are some cats scared of water, while others love it?
