Downing Street officials are preparing for the eventual announcement of Larry the Cat's death, codenamed 'Larry Bridges', mirroring royal death protocols like 'Operation London Bridge' for Queen Elizabeth II. The 17-year-old tabby, who has served as the chief mouser since 2011, has outlasted six prime ministers, becoming a beloved fixture at Number 10. Larry was adopted from Battersea Cats and Dogs Home as a pet for then-Prime Minister David Cameron's children. His role includes inspecting security and testing furniture for napping quality, alongside notable encounters with other government cats, including a rivalry with Palmerston. Officials have crafted a press release and selected photos to be released upon his passing, reflecting the care taken in managing the news of his demise. Despite preparations, Larry is reported to be in good health for his age.
