Sir Isaac NewtonAccording to various tales passed down over the years, none other than Sir Isaac Newton was experimenting with light in a darkened room and one of his most prized cats (reportedly named "Spithead") kept opening the door and disrupting the experiment. To keep his work intact and allow the cat free roam, he cut a small hole in the door and covered it with cloth. That evolved into what is today known as a pet door, suitable for both cats and dogs.
