Just had the shock of my life! A mouse just ran across my living room and disappeared down a tiny hole in the floorboard where the radiator pipe goes down. Is there ever just one??? I'm off work at the moment and I'm in this room all day every day so surely I would have notice if we were infested?? We have a cat so I'm praying he brought it in. No droppings anywhere and nothing chewed. What do we think??
