Downing Street’s “Chief Mouser”, Larry the cat, stole the show when Ukrainian President Volodymyr Zelensky visited UK Prime Minister Keir Starmer, together with France’s Emmanuel Macron and Germany’s Friedrich Merz. The 18-year-old tabby and white former stray is somewhat of a social media star with over 860,000 followers on his unofficial X account. He’s lived with six British prime ministers and has greeted countless foreign officials at a remarkable time in Britain’s political history.
