The Door Game (catfinition): A feline leisure activity. The rules and scoring system seems impenetrable to the human mind. Catologists, such as Dr. Felix Lachat, have observed that the door game apparently involves getting humans to open doors to let cats in and out multiple times. It’s speculated that the more doors that cats use, and the shorter period, appears to increase the score, as do elements such as the weather, and the time, with success at night counting for more points. Households with multiple cats report that the cats seem to take turns attempting to score.
