The cat has observed six prime ministers come and go, welcomed world leaders and royalty at the famous entrance of No 10, and is shortly set to become the most enduring uninterrupted occupant since historical figures.
While the scene of British politics has transformed significantly over the past decade and a half, the feline has remained a comforting steady presence. His lasting appeal - the kind that many leaders would covet - is now showcased in a new TV program exploring the nation's love for felines.
"Larry is certainly the character to encounter at No 10," stated one Westminster insider, adding that he "has the run of the residence."
The tabby, whose formal designation is Head Cat of the Government at the Prime Minister's residence, was adopted from an rescue center to tackle a rodent problem. His journey from stray cat in south London to government inhabitant represents a true humble beginnings story that outshines many official biographies.
When strains ran high during the coalition government, former Prime Minister David Cameron was eager to dispel any rumors of animosity between him and the country's new favorite feline. "This story is I don't love the cat - I certainly do," he declared during one government meeting.
Now a more recognized figure, the cat appears fully accustomed to the attention. Often spotted on broadcast television lingering calmly by the front door, his calm demeanor in front of audiences has become somewhat problematic for the Downing Street groundskeeper - Larry frequently goes to the main flower patch to do his business.
His government profile details the elderly tabby as passing his time greeting visitors, inspecting security defenses, and evaluating antique pieces for napping comfort. His regular responsibilities include contemplating solutions to the mouse occupancy in the house.
While Larry is the first to hold this specific position, cats have been welcomed in the corridors of government for at minimum a hundred years. "Stability is an vital part of Larry's attraction," explained one academic who has researched human-animal connections.
The cat possesses an acute sense of official occasion. "As soon as moment something happens on the road, particularly an official visit, like clockwork, he'll be out the main," remarked a Number 10 insider. "He adores the attention."
Former American leader the former president and Ukraine's leader Volodymyr Zelenskyy are among the international leaders he has impressed. However, not officials were similarly enamored.
"The former PM famously disliked him because she was a canine lover," explained one camera person who has seen several politicians attempting, and unsuccessfully, to pet Larry.
When he isn't walking the pavements, Larry's frequent resting spots include the office equipment and in-trays, but his preferred spots are on the ledges on both sides of the front door.
Larry's appeal with the public remains undeniable. There are multiple social media profiles devoted to the country's top mouser, including one with over 868,000 followers. Larry also gets letters, playthings, and snacks from around the globe and has recently been included in a book about government pets.
As chief feline, Larry naturally gets his share of complaints. One political commentator recently described him as "excessively fat and excessively idle to actually do his duties," accusing him of being "welfare reliant."
In reply, sources near to Larry have issued a stinging rebuke. They explain that he is not government paid for, with Downing Street staff voluntarily covering his costs.
