eating the wires.......

it's amazing how they manage to compress their skeletons to make their way through the holes with romex , which they walk on like Karl Walenda

and they nibble them along the way, sometimes right on down to the copper to where all 3 (12-2 say) are completely bare , and in perfect formation like the insulation simply vaporized!

i wonder what attracts them? is it the emf? the simple fact that the wiring provides a pathway? the particular material of NM providding a satisfactory knawability?
