chewy chew chew

well.....i have internet digital phone cabler blah blah blah...this means i have alot of cords running all over the place...i also like letting my ratties run all over the place...this presents a problem.....which i discovered when i was trying to get on the net and for some reason could not.....as it turns out....pie and/or pah...had chewed through the modem cord...luckily it was the side with less volts so no one got hurt.....however now i find myself.....well paranoid and chasing them around everytime i let them out....the thing is its pretty much impossible to keep them away from an area without cords....cos theres pretty much cords everywhere....im going to assume that most of you also have the internet....what do you guys do to avoid chewed cords and possible electricution?...i have resorted to keeping them in the half of the apartment that has the least cords and put my sons gate between...the problem with that is my family spends most of its time in the cord section.....so we miss our rats......comments and advice welcome
cheers
