The grey fox has a body length of 21-32 in. The grey fox's coloration is not usually grey, only parts of it are. It is cinnamon yellow with silver highlights in the face. Their legs are shorter than their red cousins. Unlike most Vulpes foxes, the grey has more ovular pupils than the more slit like ones of the red.
Grey foxes eat small mammals and wild birds, as well as insects, fruit and vegetation.
Their diet varies within their range. Some tend to be more insectivorous, some eat more vegetation, and some eat more meat, depending on what is available as prey. They rarely eat domestic fowl. They hunt at night. The pair mates for life, and form a range together.
