The striking Himalayan, produced by breeding the Siamese with several longhaired breeds over a number of generations, has been a recognized breed only since the 1950s, becoming highly popular in its short existence. It appears regularly in shows, but is also desirable as a pet because of its warm, affectionate personality. In length of coat and body shape the Himalayan has the characteristics of a Persian, but in colors it shows its Siamese heritage distinctly. Color varieties include seal point, blue, chocolate, lilac, tortie, and red. The blue eyes are round, matching those of the Siamese but less intense. Lost in the breeding, too, is the loud, demanding voice of the Siamese, another feature favoring the Himalayan. Kittens are pale, their colors developing with maturity.
