Early Life

Larry was born. He was later found as a stray in Wandsworth, south London.
Larry moved into Downing Street under David Cameron’s premiership. Adopted by Downing Street staff, he was initially intended as a pet for Cameron’s children.

Larry made his first public killing, dropping his prey on the lawn in front of Number 10.

Larry Through the Years
From a newly adopted mouser to one of Britain’s most recognizable cats, here’s Larry through the years.
Larry is the official Chief Mouser to the Cabinet Office, a role traditionally given to resident cats at government buildings to help control mice. While modern pest control has changed the practical side of the job, the position remains a beloved part of British political life.
Does Larry actually catch mice?
Yes. Although his hunting record has occasionally been the subject of good-natured media debate, Larry has caught mice during his time at Downing Street. Like many working cats, his reputation includes both genuine successes and plenty of humorous exaggeration.
Who owns Larry?
Larry is cared for by Downing Street staff rather than any individual Prime Minister. Unlike most pets at Number 10, he remains in the role when governments change.
Has Larry served every Prime Minister?
Larry arrived in February 2011 during David Cameron’s premiership. Since then, he has served under seven Prime Ministers, making him the longest-serving resident of modern Downing Street.
Why did Larry fight Palmerston?
Palmerston (RIP Palmy), the Foreign Office’s resident cat, worked just a short walk away. Their occasional encounters outside Downing Street became legendary, with several well-documented scuffles delighting photographers and earning widespread media coverage.
Does Larry live inside Number 10?
Yes. Larry lives at 10 Downing Street and is cared for by staff. Visitors often spot him lounging on the famous doorstep, inspecting official arrivals, or wandering around the Downing Street complex.
