missions was reworked to avoid a Space Transportation System (STS)-13, some sourced this to superstition and Apollo 13. The crew for what would have been STS-13 (which turned out to be STS-41C) made a humorous mission patch that included a black cat and a number 13. The mission was successful and even landed on Friday the 13th. Notable black cats The UK Government has adopted several cats from Battersea Dogs & Cats Home as mousers. Gladstone is known as Chief Mouser of HM Treasury. India, also known as Willie, was a presidential cat owned by George W. Bush and Laura Bush who lived with them at the White House. Trim sailed with Matthew Flinders as he mapped the coastline of Australia between 1801 and 1803. Trim now accompanies him on several statues in Australia and England. Hodge (fl. ) was a cat belonging to Samuel Johnson. Most of what is known about Hodge comes from James Boswell's biography and a statue of Hodge stands outside Dr Johnson's House. Oscar the "bionic" cat had his back legs sliced off by a combine harvester whilst sleeping in a field in Jersey. He was flown to the UK and received prosthetic limbs in an innovative operation in 2010. Adoption and Black Cat Day Black cats have been found to have lower odds of adoption in American shelters compared to other colors except brown, although black animals in general take more time to find homes. Some shelters also suspend or limit adoptions of black cats around Halloween for fear they will be tortured, or used as "living decorations" for the holiday and then abandoned. Despite this, no one has ever documented in the history of humane work any relationship between adopting black cats and cats being killed or injured. When such killings are reported, forensic evidence has pointed to natural predators, such as coyotes, eagles, or raptors as the likely cause. Limiting or suspending adoptions around Halloween also places more cats of all colors at risk of dying in shelters due to overcrowding. October 27 has been designated 'Black Cat Day' by Cats Protection in the United Kingdom of Great Britain and Northern Ireland, to celebrate the virtues of black cats and to encourage people to adopt an unwanted black cat. Cats Protection's own figures suggest that black cats are more difficult for them to find a new home for than other colors. In
