Why do Cats and Dogs hate each other?

Here's the optimized YouTube description: Why do cats and dogs fight? The real answer isn't what you think. Most people assume cats and dogs are natural enemies. They're not. They're two animals separated by 30 million years of evolution, running completely different communication systems — and nobody warned them before putting them in the same room. In this video, we break down the neuroscience and evolutionary biology behind why cats and dogs misread each other constantly, why a wagging tail is a threat signal in cat language, and why the pairs that do learn to coexist are doing something genuinely remarkable. What you'll learn: Why cats and dogs evolved incompatible body language systems What "referential communication" between species actually looks like The documented cases of cats and dogs that built their own private language Why the tension between them is not aggression — and not a personality flaw
