Larry the cat, the four-legged inhabitant of 10 Downing Street, is marking 10 years as Britain’s mouse-catcher-in-chief. <br />Larry was adopted and started living at Downing Street, the official home of the British prime minister, in February 2011. <br /> <br />He was brought in for his mousing skills, and became the first cat at Number 10 to be given the official title of Chief Mouser. <br /> <br />Larry is the prime minister’s cat, and he has had David Cameron, Theresa May and currently Boris Johnson as owners. <br /> <br />During his time at Number 10, he managed to keep rival cat Palmerston from the Foreign Office at bay. <br /> <br />Now Larry is only one year away from equalling Margaret Thatcher’s time at Downing Street.
