Stefan is right she is a "domestic shorthair". And I agree she is a very pretty cat. I especially like that first photo.
The pattern is Tortoiseshell and White ( or Tortie and White ) , and this particular version of Tortie & White ( where there is a lot of white and the black-based color and red-based color are in fairly big distinct patches) would be called Calico by some people in the U.S,. ( though really, by the more strict definition in CFA breed standards, Calico has more white. )
