Someday secret documents will be uncovered showing cable manufacturers actually did research to make cables more attractive to animals.

That's what I'm afraid of. Had a partial power outage in the house last night. Earth protector breaker had triggered. And a loud chewing sond could be heard from the kitchen ceiling structure along the beams - seems the #$#$& rats have gotten in there somehow. Not good news - if those cables go, the whole ceiling has to be ripped apart. And the structure is non-trivial.
