Rats and mice in wiring have been a problem for a long time, BUT, are you aware that some wiring manufacturers are using soy based plastics for insulation now? One of the car manufacturers is using a soy based foam for seats too.......sounds like rat food to me!
I like the oats/plaster of paris idea......have little statues of mouse stomachs all over the yard.....
