Bob, nicknamed the Munich Mouser, also known simply as Munich, was a cat who served as the chief mouser to the Cabinet Office from 1937 to 1943. He served under the prime minister, Neville Chamberlain, from 1937 to 1940, and his successor Winston Churchill until 1943. He therefore served in the role at the same time as Peter and Nelson, the latter who became chief mouser in summer 1940 and had a rivalry with Munich.

Chief Mouser to the Cabinet Office
Chief Mouser to the Cabinet Office is the title of the official resident cat at 10 Downing Street, the residence and executive office of the Prime Minister of the United Kingdom in London. There has been a resident cat in the British government employed as a mouser and pet since the 16th century, although modern records date only to the 1920s. Despite other cats having served Downing Street, the first one to be given the official title of chief mouser by the British government was Larry in 2011. Other cats have been given this title affectionately, usually by the British press. In 2004 a study found that voters' perceptions of the chief mouser were not completely above partisanship.
