Cat breed, whose origins are derived from cats imported to the British Isles by Roman legions, using them to fight rats. However, this legend could not be proved. The fact is that the breed originates from domestic cats living in Great Britain (however, this is not a domestic cat "British"). As a result of World War II, the existence of this breed was threatened. In the 1950s, breeders, by means of crossing with the blue perse, strengthened the population and improved the features of the breed.
