Very interesting, like vitiligo in animals.
I've got a Flickr friend who has a shot of a Blue Eyed Coyote, one in a million according to National Geographic:

Vitiligo is a chronic autoimmune disorder that causes patches of skin to lose pigment or color usually on the extremities while albinism affects ALL melanin production in an animal's cells, this means that partial albinism cannot exist. This phenomenon is known as leucism, the partial loss of all types of pigmentation, including carotenoids. Leucism causes white coloration, white patches, spots, or splotches on the skin or fur caused by genetics but Vitiligo often has other symptoms as an autoimmune disorder with some treatment options.
