I'm sure it can happen. The little fucker has chewed through 2 wires to date. Fortunately there was no power to them. It's the storage section of my attic, and i have an extension cord running down the length of the inside of the ridge that connects a few strings of c9 christmas lights, an old wall sconce, and one of those clip on metal dish thingers they use for heat lamps. He chewed one of the extension cord, and shortened my c9 string. I don't think there is any loose powered wires up there...but my cable wires go through right where he had been getting in before.
I just invested $50+ in this.....
fucking thing. I'm not sayning I won't kill the bastard once I catch him, but this seemed more cost effective than buying a higher powered weapon, and probably putting my own eye out.
