Larry has witnessed six prime ministers arrive and depart, greeted presidents and princes at the iconic entrance of No 10, and is soon set to become the most enduring uninterrupted resident since historical figures.
While the landscape of UK government has transformed dramatically over the last 15 years, the feline has remained a reassuring constant. His enduring popularity - the type that many leaders would covet - is now showcased in a new documentary series exploring the country's love for felines.
"The cat is definitely the person to encounter at Downing Street," stated one political insider, adding that he "enjoys the run of the house."
Larry, whose formal designation is Head Cat of the Government at 10 Downing Street, was taken in from an rescue center to address a rodent problem. His journey from homeless cat in Wandsworth to government resident represents a true rags to riches story that surpasses many political biographies.
When strains ran high during the political partnership, former Prime Minister David Cameron was keen to dispel any suggestions of animosity between him and the nation's new beloved cat. "This story is I dislike Larry - I do," he declared during one parliamentary session.
Now a more recognized figure, the cat appears fully accustomed to the attention. Often seen on live TV lingering patiently by the front door, his calm behavior in front of cameras has become rather troublesome for the Number 10 gardener - he frequently visits the main flower patch to relieve himself.
His government description describes the elderly tabby as passing his time greeting guests, checking protection measures, and testing antique furniture for napping quality. His regular responsibilities include contemplating answers to the rodent presence in the house.
While Larry is the first to hold this specific position, felines have been welcomed in the corridors of government for at least a hundred years. "Stability is an essential part of Larry's attraction," explained one academic who has researched people-pet relationships.
Larry possesses an sharp sense of official occasion. "As soon as moment something occurs on the street, especially an official arrival, like clockwork, he'll be out the front," remarked a Number 10 insider. "Larry loves the red carpet."
Ex- American President the former president and Ukrainian leader Volodymyr Zelenskyy are among the world leaders he has charmed. However, not leaders were equally fond.
"The former PM notoriously disliked him because she was a canine person," explained one photographer who has seen several politicians trying, and unsuccessfully, to stroke the cat.
When not walking the sidewalks, his regular sleeping spots include the office equipment and in-trays, but his favorite locations are on the window sills on both sides of the front door.
Larry's popularity with the people remains unquestionable. There are various online profiles devoted to the country's top cat, including one with over eight hundred sixty-eight thousand fans. He also gets letters, toys, and snacks from across the world and has lately been included in a book about government pets.
As chief cat, Larry inevitably gets his share of complaints. One government commentator recently called him as "too fat and too lazy to really perform his duties," accusing him of being "support reliant."
In response, sources close to the cat have issued a stinging response. They explain that Larry is not at all publicly funded, with Number 10 employees voluntarily paying his expenses.
