The swift fox (Vulpes velox) is a small light orange-tan fox, with a similar size to a domestic cat. They are found in the western grasslands of North America, such as Montana, Colorado, New Mexico, Kansas, Oklahoma and Texas. It also lives in southern Manitoba, Saskatchewan and Alberta in Canada, where it was previously extirpated. It is closely related to the kit fox (V. macrotis) and some mammalogists classify them as the same species.
