Hero999 was almost right. Cat, not Rat... I have a good looking male cat that I bet would solve his problem.
R Rock. I think he wants less rats.. I might be wrong.
And if no one tells my wife, I will ship my cat here in the US only, overnight.. I have to start a new thread on how to put a cat to sleep for 24 hours.
(joking).
I think in the old days (or where there is not a lot of City around you today), cats like mine, would sit on a fence, walk around (and probably when I was not looking take care of them). He likes to bring the snakes to the house and leave them at the door. So again I might be wrong.
Serious part:
Not sure of your environment. But high voltage in a small box with pet food might do it..
