The cat has observed six prime ministers come and go, greeted world leaders and royalty at the iconic entrance of Downing Street, and is shortly set to become the most enduring uninterrupted occupant since Pitt the Younger.
While the scene of British politics has changed significantly over the last 15 years, the feline has remained a reassuring steady presence. His enduring appeal - the type that many politicians would covet - is now featured in a new documentary series exploring the nation's affection for cats.
"Larry is definitely the person to encounter at Downing Street," commented one political source, adding that he "enjoys the freedom of the house."
Larry, whose official designation is Chief Mouser of the Government at the Prime Minister's residence, was adopted from an rescue center to address a rodent problem. His journey from stray cat in Wandsworth to government inhabitant represents a true rags to riches story that outshines many official life stories.
When tensions ran high during the coalition government, former Prime Minister the ex-PM was eager to dispel any rumors of animosity between him and the nation's new favorite feline. "This rumor is I dislike Larry - I certainly do," he announced during one parliamentary session.
Now a more established figure, Larry appears completely adjusted to the attention. Often seen on broadcast TV lingering calmly by the entrance, his relaxed demeanor in front of cameras has become somewhat problematic for the Number 10 groundskeeper - he frequently goes to the main flower patch to do his business.
His official description details the 18-year-old tabby as passing his time welcoming guests, checking security measures, and evaluating historical furniture for napping comfort. His regular responsibilities include considering answers to the mouse presence in the house.
While Larry is the initial to hold this specific title, felines have been welcomed in the corridors of power for at minimum a century. "Stability is an essential part of Larry's appeal," explained one academic who has studied human-animal connections.
The cat possesses an sharp sense of diplomatic occasion. "As soon as moment something occurs on the road, especially an formal visit, like clockwork, he'll be outside the main," remarked a Downing Street insider. "Larry loves the attention."
Ex- US leader the former president and Ukraine's President Zelenskyy are among the world leaders he has charmed. However, not officials were equally enamored.
"Theresa May notoriously disliked him because she was a dog person," said one photographer who has witnessed several politicians attempting, and unsuccessfully, to stroke the cat.
When he isn't walking the sidewalks, his regular resting spots include the printer and in-trays, but his favorite locations are on the ledges on both sides of the entrance.
Larry's popularity with the public remains undeniable. There are various social media profiles devoted to the nation's top mouser, including one with over 868,000 fans. He also receives letters, toys, and treats from around the world and has lately been featured in a publication about political pets.
As chief feline, he inevitably receives his portion of criticism. One government analyst recently described Larry as "too overweight and excessively idle to really perform his job," accusing him of being "welfare dependent."
In reply, sources near to Larry have released a strong rebuke. They clarify that Larry is not publicly paid for, with Number 10 employees voluntarily paying his expenses.
