Paul Casey was inspired to create the breed from a conversation he had with Louis Leakey.

[1] Casey started with breeding a female Traditional Siamese to a Turkish Angora.

The widespread publicity worked in Casey's favour and hundreds of people inquired about the breed.

[1] The California Sprangled's markings are similar to that of a leopard or cheetah with well defined spots and musculature.
