Years ago, my wife brought 3 orphan baby cats, into our home. They were Great buddies.
One of the 3, was a chewer.
My wife named him, Nicholas. He used to chew, the cable wires, going to the TV.
He used to climb up on the counter, at night, and chew the cabinet handles.
One morning, my wife clicked the Cable Box, to turn the TV on, and nothing happened.
Nicholas Chewed, the 120 volt power wire in two, while it was plugged in.
Nothing, happened to him.
After that, I ran ALL our wires and cords, through garden hoses.
