Mink are members of the weasel family, along with badgersriver otters, and weasels. The American mink (Neogale vison) is the only mink found in the United States. It is a native species in Yolo County. Per the California Department of Fish and Game range maps, it lives in all parts of the county, including in Davis. It's generally nocturnal, and therefore not often seen, but it does occasionally venture out in the daytime. Have you seen one?
