Larry the Cat Marks 15 Years as Downing Street’s Chief Mouser
Larry the Cat, Downing Street’s long-serving Chief Mouser, marks 15 years at Number 10 after serving under six UK prime ministers and becoming a symbol of continuity in British politics.
Feb 16, 2026

There are stability signals you can read in polling tables and budgets, and then there’s the less quantifiable comfort of a dozing tabby on the doorstep. This week Larry, the long-time resident of Number 10, quietly marked 15 years as Britain’s official Chief Mouser, a milestone that has prompted fond recollections from staff, a fresh round of photo galleries, and the predictable flood of affectionate headlines.
Larry arrived at Downing Street in February 2011. He was adopted from Battersea Dogs & Cats Home during the premiership of David Cameron. At the time, reports of mice inside the historic government building had made headlines. Downing Street confirmed that Larry’s appointment was partly practical: he would help deal with the rodent issue in the centuries-old property. But his role quickly expanded beyond pest control.
Official descriptions of the Chief Mouser’s duties, often delivered with British humor, include “greeting guests,” “inspecting security defenses,” and “testing antique furniture for napping quality.”
Larry was estimated to be around four years old when he moved in. Fifteen years later, he is considered a senior figure in Downing Street, at least in symbolic terms.

Serving Six Prime Ministers
One of the most striking aspects of Larry’s tenure is his longevity. Since 2011, he has lived at Number 10 under six prime ministers:
- David Cameron
- Theresa May
- Boris Johnson
- Liz Truss
- Rishi Sunak
- Keir Starmer
In a political climate often marked by rapid turnover, Larry has provided an unusual sense of continuity. Media outlets including the Associated Press and ITV News have highlighted how the cat’s presence offers a light-hearted counterpoint to serious political events. For many observers, Larry has become a symbol of institutional stability, a reminder that while leadership changes, some traditions remain.

A Public Figure in His Own Right
Over the years, Larry has grown into something of a celebrity. Photographers stationed outside Downing Street frequently capture him stretching across the doorstep or observing journalists from a safe distance.
He has appeared in images alongside visiting dignitaries, government officials and Christmas decorations. On more than one occasion, he has casually wandered into live television shots, unintentionally stealing attention from the day’s political messaging.
News agencies have published dedicated photo galleries documenting his life at Number 10, turning him into an unlikely but consistent fixture in Britain’s media landscape.
The Reality of the Chief Mouser Role
Despite the affectionate coverage, Larry’s job is not entirely ceremonial. Downing Street has confirmed that pest control remains part of his purpose. The historic building, like many old properties in London, can attract rodents.
Importantly, Larry is not the personal pet of any prime minister. He is cared for by Downing Street staff, which helps explain why he remains in residence regardless of who occupies the top political office.

This arrangement has allowed Larry to transcend party politics. He does not belong to any administration, he belongs to Downing Street itself.
Why the Public Loves Larry
Part of Larry’s appeal lies in timing. He arrived during an era when social media was rapidly reshaping how the public interacts with political institutions. Images of him lounging outside the iconic black door are easily shared, meme-able and comforting.
In times of political uncertainty, the sight of a familiar cat calmly surveying his territory offers a small but meaningful sense of normalcy. As Associated Press noted in anniversary coverage, Larry’s 15-year milestone has prompted warm tributes and reflections on his unusual “career” at the heart of the British government.
A Living Piece of Modern Political History
At approximately 18-19 years old, Larry is now considered a senior feline. Yet he continues to patrol the Downing Street forecourt and appear in official photographs. His 15-year anniversary is more than just a charming lifestyle story. It underscores how even in the most formal institutions, personality and tradition matter. Larry has quietly witnessed leadership contests, Brexit debates, general elections, and international crises, all from his vantage point near the famous door of Number 10.
In a world of fast-moving headlines, Larry’s steady presence has become a reminder that history is not only shaped by speeches and summits, but also by the small, everyday details that humanize power.
Fifteen years after padding into Downing Street as a rescue cat from Battersea Dogs & Cats Home, Larry remains on duty, Britain’s most famous mouser, and perhaps its most consistent public servant.
