Mouse in the house

Saw the mouse trap closed this morning. Hopefully that is the last mouse caught. I've caught 3 in 3 days in our flat now, with our Rentokill mouse friendly mouse trap. Apart from I've been chucking them down the drain at the side of the road after I've caught them. I hope mice can swim. Some people spotted me throw a mouse into the sewer on Sunday night, with a mixture of puzzlement and horror. I hope we've caught the last mouse now.
