Larry has observed half a dozen prime ministers come and go, welcomed world leaders and princes at the famous entrance of Downing Street, and is soon set to become the longest continuous resident since Pitt the Younger.
While the scene of UK government has transformed significantly over the past decade and a half, Larry has remained a comforting steady presence. His enduring popularity - the type that many leaders would covet - is now featured in a upcoming documentary series exploring the country's love for cats.
"Larry is definitely the character to encounter at No 10," commented one Westminster source, adding that he "has the freedom of the house."
The tabby, whose official designation is Chief Mouser of the Cabinet Office at 10 Downing Street, was adopted from an animal shelter to address a rodent problem. His journey from homeless feline in south London to government inhabitant represents a true humble beginnings story that surpasses many official biographies.
When tensions ran strong during the coalition government, former leader the ex-PM was keen to dispel any suggestions of dislike between him and the nation's new beloved feline. "The story is I dislike the cat - I certainly do," he declared during one parliamentary session.
Now a more established figure, Larry appears fully accustomed to the attention. Often spotted on live television waiting calmly by the entrance, his relaxed behavior in front of cameras has become somewhat problematic for the Number 10 gardener - he frequently goes to the front flower patch to relieve himself.
His government description describes the 18-year-old tabby as spending his time greeting visitors, inspecting security measures, and testing antique pieces for napping comfort. His day-to-day responsibilities include considering answers to the mouse occupancy in the residence.
While Larry is the first to hold this particular position, cats have been accepted in the corridors of power for at minimum a hundred years. "Consistency is an vital part of Larry's appeal," explained one academic who has researched human-animal connections.
The cat possesses an sharp sense of diplomatic occasion. "As soon as minute something happens on the road, particularly an official arrival, like clockwork, he'll be outside the main," commented a Number 10 insider. "He adores the attention."
Former US leader the former president and Ukraine's leader Volodymyr Zelenskyy are among the world figures he has charmed. However, not all leaders were similarly enamored.
"The former PM famously disliked him because she was a canine lover," said one photographer who has witnessed several MPs attempting, and unsuccessfully, to stroke Larry.
When not walking the pavements, his regular resting places include the printer and desk organizers, but his preferred spots are on the ledges on both sides of the front door.
The cat's popularity with the people remains undeniable. There are multiple social media profiles dedicated to the country's chief cat, including one with over 868,000 followers. He also receives fan mail, playthings, and snacks from around the globe and has lately been included in a book about political animals.
As chief feline, he naturally gets his share of complaints. One political analyst recently described Larry as "excessively overweight and excessively lazy to actually perform his duties," claiming him of being "support reliant."
In response, insiders close to Larry have issued a stinging response. They explain that Larry is not government paid for, with Number 10 staff willingly covering his expenses.
