Britain’s most famous cat hits 19 as Larry’s long reign continues

Larry the cat, the long serving Chief Mouser to the Cabinet Office, has turned 19, prompting an outpouring of affection and humour online as Britain’s best known feline reaches another milestone at the heart of government.

First adopted from Battersea Dogs and Cats Home in 2011, Larry was brought in to tackle a rodent problem at 10 Downing Street. Over time, his role has grown far beyond pest control. He has become a familiar and oddly comforting presence during years of political upheaval, leadership changes and global crises, often photographed lounging on the doorstep or appearing unimpressed by passing politicians.

Larry now holds the title of the longest serving Chief Mouser in British history. Across his tenure, he has served under six Prime Ministers, witnessing shifts in power, policy and public mood from a position of quiet indifference. His longevity has turned him into a symbol of continuity at Westminster, particularly during periods when leadership turnover felt relentless.

Official accounts marked the occasion by acknowledging his birthday, while fans across social media were quick to share tributes, memes and throwback photos. Many posts celebrated Larry as the one constant in British politics, with users joking that he has outlasted political careers, cabinets and campaign promises alike. Others praised his apparent talent for choosing sunny spots on the doorstep at exactly the right moment for photographers.

The birthday also sparked renewed discussion about Larry’s semi official status. Despite his title, it has long been noted that Larry prefers naps, casual strolls and public appearances to active mousing. Still, his popularity has never waned. Supporters often point out that morale boosting and national distraction have become part of his unofficial duties, particularly during tense news cycles.

Animal welfare organisations also used the moment to highlight Larry’s adoption story, reminding followers that one of the country’s most recognisable residents came from a rescue shelter. That detail has been widely shared as part of the birthday conversation, adding a softer note to the celebrations.

As Larry enters his twentieth year, there is little sign of him stepping back from public life. His continued presence offers a rare sense of familiarity in an environment defined by change.
