The Chief Mouser to the Cabinet Office is the title of the official resident cat of the Prime Minister of the United Kingdom at 10 Downing Street. There has been a resident cat in the English government employed as a mouser and pet since the 1500s, although modern records date only to the 1920s. Though other cats have served Downing Street the first one to be given the official title of Chief Mouser by HM Government is Larry in 2011. Other cats have been given this title affectionately, usually by the British press. In 2004 a study was done showing that voters' perceptions of the Chief Mouser were not completely above partisanship.
History
There is evidence of a cat in residence in the English government dating back to the reign of Henry VIII, when Cardinal Thomas Wolsey placed his cat by his side while acting in his judicial capacity as Lord Chancellor. Official records, however, released into the public domain on 4 January 2005 as part of the Freedom of Information Act 2000 only date back to 3 June 1929, when A.E. Banham at the Treasury authorised the Office Keeper "to spend 1d a day from petty cash towards the maintenance of an efficient cat". In April 1932, the weekly allowance was increased to 1s 6d. By the 21st century, the mouser was costing £100 per annum. The cats do not necessarily belong to the Prime Minister in residence and it is rare for the Chief Mouser's term of office to coincide with that of a Prime Minister. The cat with the longest known tenure at Downing Street is Wilberforce, who served under four different Prime Ministers: Edward Heath, Harold Wilson, Jim Callaghan, and Margaret Thatcher. The post has been held by Larry since 2011, the first to be given the title officially. The departure of the previous incumbent, Sybil, was in January 2009. Sybil, who began her tenure on 11 September 2007, was the first mouser for ten years following the retirement of her predecessor Humphrey in 1997. Sybil was owned by the then Chancellor of the ExchequerAlistair Darling, who lived in 10 Downing Street while the then Prime Minister, Gordon Brown, lived in the larger 11 Downing Street. It was reported that Sybil did not settle in London, and returned to Scotland to live with a friend of the Darlings. Sybil died on 27 July 2009. In January 2011, rats were seen in Downing Street, "scurrying across the steps of Number 10 Downing Street for the second time during a TV news report," according to ITN. There being no incumbent Chief Mouser at that time, the Prime Minister's spokesman said there were "no plans" for a cat to be brought in to tackle the problem; however, the following day, newspapers reported that the spokesman had said there was a "pro-cat faction" within Downing Street, leading to speculation that a replacement might indeed be brought in to deal with the problem. On 14 February 2011, it was reported that a cat called "Larry" had been brought in to address the problem. The London Evening Standard reported that the cat had been selected by David Cameron and his family, from those at Battersea Dogs & Cats Home. In September 2012, it was reported that Prime Minister David Cameron had sacked Larry from the post of Chief Mouser, in favour of Chancellor George Osborne's tabby cat, Freya, as the new Chief Mouser to patrol Numbers 10, 11, and 12. Some sources described the new arrangement as a "job share" to avoid any hurt feelings. Chief Mousers in the past have overlapped, or been phased in – though the position can and has remained vacant for extended periods of time. Larry is the only Chief Mouser listed on the official web site for Number 10. In November 2014 Freya was exiled from Downing Street leaving Larry as the Chief Mouser.
Partisanship study involving the Chief Mouser
Robert Ford, a political scientist at the University of Manchester, reported on a YouGov survey on partisan reactions to the Downing Street cats. Participants in the survey were shown a picture of Humphrey, the Chief Mouser appointed by Margaret Thatcher, and told that he was either Thatcher's cat or Tony Blair's cat. Affinity for the cat divided along partisan lines: Conservative voters liked the cat far more when they were told he was Thatcher's and Labour voters liked the cat far more when they were told he was Blair's. Ford concludes that partisanship shapes reactions to everything a politician does, however trivial, similar to the halo effect observed by psychologists.
