Every once in a while one runs across a news item like this one about an apartment building in Šabac where the residents were left without telephones, electricity and heat because rats ate through the cables. A little gross, yes, and I know there is nothing special about Šabac here because rats are at home pretty much anywhere (but most of all, I think, in the NYC subways). But my question is: electrical cables? They will really eat metal? Wouldn't they be shocked? Your animalistic analyses, please.
Update: Andras found this answer from a "nuisance wildlife control company" in Orlando, Florida. It's illustrated, high "blecchhhh" factor.
