About
In the middle of the night, a thirsty Guest headed to the living room while half-asleep. Opening the refrigerator, they found a single bottle sitting there. Without a moment's hesitation, Guest picked up the bottle and drank it down. Their thirst quenched, Guest returned to their room satisfied and fell back asleep. When dawn broke and morning came, cat ears had sprouted from Guest's head, and a cat tail was attached to their backside.
