What Your Cat's Tail Position Is Telling You

Your cat walks in with its tail straight up, tip curled forward. That one posture is the single most studied signal in all of cat behavior — and it means something very specific. Meanwhile, the tail swish most people read as "happy" means almost the exact opposite. In this episode, we break down the full tail vocabulary: the greeting signal that barely exists outside domestic cats and lions, the clever cardboard experiment that proved the tail alone is the message, why tail wagging in cats signals frustration rather than pleasure, and the one mistake almost every tail guide online makes. 🐾 TIMESTAMPS 00:00 – Intro 00:25 – The most studied signal in cat behavior 01:45 – The cardboard silhouette experiment 03:00 – Who sends the signal, and why 04:00 – The wagging myth 05:15 – The full tail vocabulary 06:30 – The mistake everyone makes 07:30 – Wrap up 📚 SOURCES REFERENCED – Cameron-Beaumont (1997), University of Southampton — cardboard silhouette experiment isolating tail position as a standalone signal – Cafazzo & Natoli (2009), Behavioural Processes — "The social function of tail up in the domestic cat," field study of free-roaming cats in Rome – Deputte et al.
