This is a controversial breed because its color is sex-linked, and with rare exceptions only females are known. If males are born, they usually do not live long. For show acceptability in Great Britain the blue and cream hairs in the coat must be evenly intermingled. In United States shows the coat must have patches of blue and cream. This breed, the result of crossing a Blue and a Cream, has a long, soft coat and coppery or orange eyes. Many have a blaze of cream on the forehead. Though not common, particularly because of the breeding problems, the Blue-cream Longhair is certainly one of the attractive longhaired cats.
