Low to the ground, flat and broad and shortish tails, ginger colouring.

Not a Mouse at all.

Try VOLE (we have loads living in and around compost heap on lottie). Can never remember which is which (we have Bank and Field) one has shortish tail, the other virtually none (so you can't tell if they are running forwards or backwards!!). I'm guessing with tails they are FIELD VOLES

LCG ;-))
