Why Cats and Dogs Fight — It's Not What You Think

A dog spots a cat across the room. Every muscle tightens. The cat freezes. The dog lunges. We watch that scene and say: of course. They've always hated each other. But what if the feud was never real — just two animals running completely opposite communication systems, dropped into the same living room, misreading each other's every signal? ✅ Why a wagging dog tail looks like an aggression warning to a cat ✅ What "direct eye contact + straight approach" means in dog vs. cat social language ✅ Why a cat lying on its back with belly up is not an invitation — it's a combat position ✅ The chase reflex that fires before the dog has made any conscious decision at all ✅ The early socialization window that rewrites the default from emergency to ordinary ✅ What coexistence between a cat and dog actually looks like — and why it's not a miracle ⏱ Chapters 0:00 — The scene everyone thinks they understand 0:23 — The twist: it's a translation failure 1:03 — The chase reflex 3:38 — Body language decoded 6:11 — They can learn 7:33 — What coexistence actually looks like 8:42 — The cartoon myth 10:57 — The feud was never real Have a cat and a dog at home?
