Beatrix Potter said this quote

Sunday, January 27, 1884. -- There was another story in the paper a week or so since. A gentleman had a favourite cat whom he taught to sit at the dinner table where it behaved very well. He was in the habit of putting any scraps he left onto the cat's plate. One day puss did not take his place punctually, but presently appeared with two mice, one of which it placed on its master's plate, the other on its own.
