Came across this product after our 6-y/o tortie cat got bored while sitting in the vicinity of an electric heater during a cold day. She decided to chew on the 120V plugged-in power cord (!). Luckily, we caught her before she chewed all the way through. She put quite a few little holes in the insulation, though.
