Question: What kind of animal served under Sir Edward Richard George Heath to catch mice?
Context: The ship's cat has been a common feature on many trading, exploration, and naval ships dating to ancient times.  Cats have been carried on ships for many reasons, most importantly to catch mice and rats.  These vermin aboard a ship can cause damage to ropes, woodwork, and more recently, electrical wiring.  Also, rodents threaten ships' stores, devour crews' foodstuff, and could cause economic damage to ships' cargo such as grain.  They are also a source of disease, which is dangerous for ships that are at sea for long periods of time.  Notably, rat fleas are carriers of plague, and rats on ships were believed to be a main spreader of the Black Death. Sir Edward Richard George Heath, (9 July 1916 – 17 July 2005), better known as Ted Heath, was a British politician who served as Prime Minister of the United Kingdom from 1970 to 1974 and Leader of the Conservative Party from 1965 to 1975.  He was a strong supporter of the European Communities (EC), and after winning the decisive vote in the House of Commons by 336 to 244, he led the negotiations that culminated in Britain's entry into the EC on 1 January 1973.  It was, says biographer John Campbell, "Heath's finest hour".  Although he planned to be an innovator as Prime Minister, his government foundered on economic difficulties, including high inflation and major strikes.  He became an embittered opponent of Margaret Thatcher, who supplanted him as party leader in 1975. Wilberforce was a cat who lived at 10 Downing Street between 1973 and 1986 and served under four British Prime Ministers: Edward Heath, Harold Wilson, Jim Callaghan and Margaret Thatcher.

It was created on 4 February 1686 for Robert Guldeford.  The title became extinct on his death in circa 1740.  The Guldeford (or Guildford) family descended from Sir John Guldeford (d. 1493), Comptroller of the Household during the reign of King Edward IV.  After supporting the Earl of Richmond (later Henry VII), Sir John and his son, Sir Richard Guildford, were attainted by Parliament.  However, they were restored to favour after the accession of Henry in 1485.  Sir Richard gained prominence under Henry and notably served as Master of the Ordnance.
