Palmerston, the iconic chief mouser of the Foreign Office, has died peacefully at the age of six in Bermuda, where he had taken on a new role as a “feline relations consultant” to the Governor. The rescue cat from Battersea Dogs and Cats Home captured hearts during his four-year tenure in Whitehall and continued to charm in his semi-retirement.
A Diplomatic Legacy
Palmerston became a household name during his time at the Foreign Office, where he was celebrated not only for his role in pest control but also for his endearing personality. He officially joined the department in 2016 and quickly became a beloved figure among staff and visitors alike. His playful antics and charming presence made him a social media sensation, amassing over 105,000 followers on Twitter.
After retiring from his Whitehall duties in 2020, Palmerston enjoyed a quieter life, but the call of public service proved irresistible. In February 2025, he returned to the spotlight, taking up his unique position in Bermuda, where he continued to represent the spirit of diplomacy in a warmer climate.
Tributes Pour In
The news of Palmerston’s passing was shared on his social media account, which stated: “Palmerston, Diplocat extraordinaire, passed away peacefully on 12 February. ‘Palmy’ was a special member of the Government House team in Bermuda, and a much-loved family member.” The tribute highlighted his gentle nature and the void he leaves behind.

Former rivals and colleagues have expressed their condolences. Larry the Cat, the chief mouser at Number 10, acknowledged their long-standing feud with a heartfelt message: “Farewell old friend x.” Labour MP Sarah Champion succinctly added, “RIP.” These sentiments reflect the profound impact Palmerston had on those around him.
A Life of Service
In a letter written before his retirement, Palmerston expressed his desire to step back from the front lines, having enjoyed the quieter life during the COVID-19 pandemic. He noted, “I have found life away from the front line relaxed, quieter, and easier,” while also underscoring his role in fostering relationships and celebrating diversity within the Foreign Office.
His former colleagues fondly remember his time at the Foreign Office. Jon Benjamin, director of the department’s Diplomatic Academy, reminisced about a humorous encounter: “He left us a slightly chewed dead mouse next to my desk in @UKDipAcademy once, and we were of course not very grateful.” Such anecdotes highlight the unique character and charm that Palmerston brought to his role.
Why it Matters
Palmerston’s legacy extends beyond the realm of a mere office pet; he embodied a unique blend of warmth and diplomacy that resonated with the public. His passing leaves a significant gap in the landscape of the Foreign Office, reminding us of the power of companionship and the lighter side of political life. As we reflect on his contributions, it’s clear that even the smallest members of society can play a pivotal role in shaping our cultural narrative.
