Simpkin is the name of the resident cat at Hertford College, Oxford. The college's tradition of keeping a mouser was started in the early 1970s by the former college principal Geoffrey Warnock.[1] The college's cat is named Simpkin after a character in the children's book, The Tailor of Gloucester, by Beatrix Potter.[2]
To date, Hertford College has had four college cats called Simpkin. The first three were black with white chest and feet, but the current one, Simpkin IV, is entirely black.[1]
