Rat or mouse feet are visible. Compared to the rest of the body, they usually have less hair on them, with partial or clear skin visible. They are not hairless. Artistic representations may vary this detail and may omit the hair; this does not preclude the tag.
At the end of each toe, there are usually long nails or claws (depending on the artistic representation).
In anthropomorphic representations of rats or mice, note whether they are depicted in an animal or human form, as this will determine whether the tag applies.
