Animals React As Herds

Instead of individually reacting, the various animals of Minecraft should collectively respond when a nearby member of the herd is attacked.

Cows and sheep flee together in one direction as a stampeding herd.

Pigs and rabbits scatter in different directions.

Chickens run around in swerving circles.

This would reward players who think creatively and use the environment to their advantage, while also making the world and its creatures feel a little more real.
