Droppings And Droplets

My Sister-In-Law had a Mouse Man visit today as some mice have been taking the Micky in her house lately. Most of them have been caught/shot/trapped (17 up to now), but there are a cheeky few, possibly the commando/SAS type, who insist on popping into her house when she out. Hopefully this Mouse Man will get to the bottom of it by the end of the third visit, today being the first.
