Ask-a-Dave's-Gardener: Keeping squirrels & rodents from chewing pump cords, 1 by Boofish1

I have a free-standing fountain for squirrels, birds, bees, etc. to drink from. The electric cord for the pump has to go a couple of yards to be plugged in, and critters continually chew through them. I\'ve looked online and seen many suggested fixes (piping, rodent tape, mesh covers) but reviewers typically comment that they don\'t work. The cover would have to be wide enough for the plug to fit through, and that width would allow rodents to get in. Any ideas?
