We have seen mice in people's cars!

Sure some of them are real cute.    But when you are told that one ate up
the wiring in your car (new car), I bet the cute is gone.   We have seen a
lot of it as of late.    We had a car with 6000 mile on it.   Wires all over the 
dash damaged.   I hear peppermint and oil sprayed around the car will keep them out.
True?    Not sure.    Maybe just keep food out of the car?   Bad darn problem anyway.
