Trivia: Chief Mouser is the resident cat of what U.K. government office?
Royal Mint
Cabinet Office
Old Bailey
The Royal Family
The correct answer is Cabinet Office
So why is this answer correct? : In the 1920s, British Prime Minister Ramsay MacDonald began the informal tradition of having a Chief Mouser position — held by a cat — in the Cabinet Office of 10 Downing Street. The tradition has continued to this day with Larry, the first feline to officially hold the title. Former Prime Minister David Cameron adopted Larry in 2011, and the cat has remained at Downing Street even as prime ministers have come and gone.
