This domestic cat was stimulated into attacking this man because he was behaving in a way which indicated to the cat that he was hostile due to the noise and general pandemonium he was generating. That is my reading of the situation. The Daily Mail says the cat is a jerk. I’d say the human is a jerk. But then I would, wouldn’t I? It is a genuine cat attack which is rare to see in video on YouTube. Domestic cats are very slow to attack humans for obvious reasons. It makes me smile because it shut the guy up very quickly!
