Why and how do cats purr? That’s what Reid wants to know. It sounds like a simple question, but it leads us to a deep challenge: Can we ever understand cats? To find out, we launch a full-scale cat purr investigation. You’ll hear from a puzzled veterinarian, a scientist who studied her cat’s annoying purr, and the author of purring.org, the premier cat purr research website. It’s a purr-fect episode for everyone who’s curious about cats.

Learn more about cat purrs - and cat smiles - in our bonus interview episode! It’s available on our ad-free podcast feed on Patreon. It’s just $1/month to get access to all our bonus episodes. Pledge at patreon.com/tumblepodcast.
