Do you keep your cat plugged in too long? Fully-charged felines, plugged in but not doing anything, consume an estimated 80MW of electricity annually, enough to power all the illegal video poker games in a western suburb for a month. Overcharging has also been linked to unusual cat behavior, such as wanting to come inside, then asking five minutes later to be let out. Save the planet, and your cat. Unplug your kitty.
