Lights go on, lights go off
If your hands are full, you can always rely on the furry paws of your pet cats and dogs. Dogs can fetch newspapers and beer, while cats make excellent light switchers. Their paws are the right size to flip a switch on and off when you need them to or not.
In this guy’s story, it was more of the “or not” that was a problem. They taught their cat how to turn the lights on and off, and over time, it became a game to the feline. It would do it for fun, or maybe it knew that it annoyed the owner. Cats are lovable jerks.
