I have a vague childhood memory of watching a horror movie back in the 70’s. The only thing I remember about it is a scene where a man is outside his house (possibly a mansion) and he sees a cat in the driveway. He whistles at the cat and in the next scene the cat isn’t just dead, it’s actually mangled from his whistling.
I saw it in the 70’s but it’s probably older than that. I can’t remember if it was in B/W or color. English speaking. I’m fairly certain that it was part of an anthology movie.
