Get yourself a pussy cat, they love to get those pesky mice. My girly cat Mildred used to bring the dead ones home for me but minus their heads
She brought one home one day and dropped it on the doorstep but it was still alive and was then running round the kitchen with a big hole in it's tummy and it's guts hanging out
I was stood on the windowsill screaming at my b/f to get rid of it..........
