Larry the cat, the long-serving “Chief Mouser” at 10 Downing Street, welcomes his seventh prime minister, as Andy Burnham takes over the role, replacing Keir Starmer. Sources say Larry moved into the prime minister’s residence on February 15, 2011, when David Cameron was leader. He was adopted from a London animal shelter after being found with an estimated age of about four years. Larry is recruited for rodent control and has continued in the role through multiple administrations. Reporting notes that he has lived through six prime ministers, from Cameron to Starmer, and has been present during major events in recent UK political history, including Brexit, the COVID-19 period and “partygate,” as well as the short tenure of Liz Truss. Sources also highlight Larry’s routine and public profile, including messages posted on his X account run by an anonymous user. The account describes Larry’s preferences for meals and includes occasional complaints and light political jabs, with mentions of Reform UK and U.S. President Donald Trump. Sources further note that Larry has shared the residence with the incoming family’s pets in recent years, though the presence of Burnham’s dog is described as unclear.
