Mark Twain was rather besotted with cats. In 1898, Twain's relationship with his cats was reported "Twain would call the cats to 'come up' on the chair, and they would all jump up on the seat. He would tell them to 'go to sleep,' and instantly the group were all fast asleep. They would remain so until he called 'Wide awake!' when in a twinkling up would go their ears and wide open their eyes."
