Downing Street officials are preparing a 'media plan' to announce the eventual passing of Larry the cat, The Independent understands.
Larry has become a much-loved figure in Downing Street and can often be seen at the door of Number 10 during major political events and news broadcasts.
The 17-year-old 'chief mouse hunter' is thought to be in his final years, having already outlived the average lifespan of a tabby cat.
Government sources said The Times that a press release and graphics are being prepared “ready for the sad day he passes away.”
It is reported that the photos selected for publication after his death was announced are being stored in folders on IT System 10 as part of a plan to inform the public.
While one source said Larry is currently “doing pretty well,” another said, “We felt it had to be handled with such caution.”
The cat, who was adopted through Battersea Cats Home, was first brought to Downing Street by David Cameron as a pet for his children and has since outlived five prime ministers.
The Cabinet Office website has a biography of the beloved cat, which states: “Larry has been a guest here since February 15, 2011. He is the first cat at number 10 to be given the official title of Chief Mouser.
“Larry was recruited from Battersea Dogs and Cats Home on recommendation for his mouse skills. He joined the Number 10 household and has made a significant impact.”
It added: “He has captured the hearts of the British public with press teams often camped outside his front door. In turn, the nation sends him gifts and treats every day.
“Larry spends his day greeting guests at the home, inspecting security and testing antique furniture for sleep quality.
“His daily responsibilities also include coming up with a solution to the house’s mouse infestation. Larry says this is still ‘in the tactical planning stages.’”
