Elsie the cat has a set of 120 buttons programmed with words. She uses them to lie, swear, apologise, express grief and frustration and love to her human, the author Mary Robinette Kowal, who talks about what's involved in learning to communicate via language buttons with companion animals. And animal behaviour expert Zazie Todd explains how animals might be interacting with human language.

This is the first half of a two-parter: in the next episode, some talking dogs - and their humans - come to visit, and we hear about the kinds of things you find out about what your animal friend is really thinking, and how it changes the ways you communicate with other humans too.
