Why do mice have such long tails? Several wood mice live in the dry stone wall a couple of metres from my back door. Most of them have tails that are longer than their bodies. Occasionally one has a tail only about half as long, which I suspect has been shortened accidentally. However, this doesn’t seem to affect either the behaviour or agility of the mouse.
