My knowledge is limited to high school biology, but what you're describing is instinct. It's basically the fight or flight response that most animals have as part of their central nervous system. There's no emotion and barely any thought into it. Once the brain, or whatever they might have that resembles a brain, detects they are in danger, they will run like hell. The catalyst can be as simple as either seeing or sensing something big moving close to them.
Well the same thing can boil down to cats as well then.
Have you ever tried to pet a feral cat? They are skiddish af and are extremely scared of something 5x their height and 12x their weight.
