Larry, the official cat of 10 Downing Street, has become the longest-serving feline in his role as the Chief Mouser [1].
His tenure provides a rare point of continuity in the United Kingdom's political landscape. As prime ministers and cabinets change, Larry remains a constant presence at the heart of British government, serving as an unusual symbol of stability during turbulent periods [1].
Larry reached this historic milestone in February 2026, completing 15 years of service at the Prime Minister's residence [1], [2]. This duration of service establishes him as a record-holder for the position [1].
The role of the Chief Mouser is a traditional fixture at the London address, though few have maintained the post for as long as Larry. His presence at 10 Downing Street has transitioned from a simple pest-control appointment to a recognized piece of the residence's cultural identity [1].
While political leadership in the UK has seen significant shifts, the feline resident has remained undisturbed by the changing administrations. This longevity has made him a point of interest for both citizens and international observers following the internal workings of the UK government [1].
“Larry has become a record-holder for the longest-serving feline in that role”
Larry's record-breaking tenure reflects a British penchant for maintaining tradition amidst political volatility. By serving through multiple administrations, the Chief Mouser has evolved from a functional role into a symbolic mascot of institutional permanence, offering a lighthearted contrast to the high-pressure environment of 10 Downing Street.
