In Lexicat part 1, we met the author Mary Robinette Kowal and her cat Elsie, and learned about how they communicate via a set of buttons programmed with words. In part 2, two talking dogs, Bastian and Parker - and their humans, Joelle Andres and Sascha Crasnow - join us too, and explain how they discovered some very unexpected things about what their animal companions are thinking and feeling thanks to the buttons, and how they changed the ways they communicate with other humans too. And animal behaviour expert Zazie Todd gives us some tips for interpreting cats’ and dogs’ body language.
