   Where I work we have a horrible problem with the ethernet cables being   
   chewed on.  Thankfully, they seem to have stayed away from the power   
   cables so far.  At least one building I know of burned to the ground   
   because of rodent attacks on the power wires, and it wasn't so old a   
   building as to have old romex either.
