Larry the Downing Street cat and Palmerston the Foreign Office cat square off outside Britain's Prime Minister's official residence 10 Downing Street, London, Jan. 29, 2018. Palmerston the cat has become a popular addition to the Foreign Office. But senior diplomats are concerned that he has become rather too well-loved. Staff have been asked to avoid giving the department's chief mouser tidbits to eat amid office rumors that he has become less effective at his job of catching mice. (Photo/Agencies)
