I keep a Shop Vac, wrapped in plastic, on the deck to help me clean up little accidents from the bunnies when they go out for exercise.
The bunnies love their exercise time, but they don't like the noise of the vacuum cleaner.
I picked up the cord. Somehow the bunnies orchestrated an attack on the vacuum, chewing almost through the cord. I saw exposed copper wire and three distinct wires that normally should be hidden by a tough outer cover.
I got out the electrical tape and started working to repair the cord only to see another section chewed almost through.
The bunnies were thorough in their attempt to disable the vacuum cleaner monster that they cower from when it's running. Such brave bunnies.
