The Snowshoe is a breed of cat originating in the United States of America in the 1960s. Snowshoes were first produced in Philadelphia when a Siamese breeder's cat gave birth to three kittens with white feet. The breeder, Dorothy Hinds-Daugherty, then began a breeding program to produce what were originally called 'Silver Laces', crossing the strangely marked Siamese cats with bi-color American Shorthair cats and other breeds. When Hinds-Daugherty left the program, Vikki Olander began working with the cats and recruited new breeders, as well as worked towards full recognition within cat associations. Despite having existed for 45 years, Snowshoes are rare due to the difficulty of reproducing the correct coat markings. The marks are based on recessive genes for color points and on the co-dominant but variably-expressed piebald pattern gene, making it difficult to predict the appearance of offspring.
