I have a horse in the barn who keeps unplugging the cord for the water tank heater in there, which provides their drinking water. She's a youngster and I really dont understand why she does this. I never had other horses do this. I cant really keep her away from the outlet, so I'm looking for some way to make the cord unpluggable. I suppose I could build a wooden box with a hinged door to mount over the outlet, but that takes work. I'm looking for a simple solution, which allows me to still get to the (GFI) outlet.
Any ideas?
Note: Unplugging the cord from the outlet causes the water tank to freeze for her and the other horses, and they need water. Outdoor horses can temporarily eat snow for "water" but not those indoors. (Of course the outdoor ones have heated water tanks too).
