Its eyes are encircled by white. The iris is yellowish, and its pupils contract to small circular slits in sunlight. Its ears are grey with a yellowish tinge on the back and a darker rim, but with whitish hair in front and in the ear pinnae. Its rounded ears are set low on the side, so that it can peer over an object and show only a relatively small part of the head above the eyes without depressing the ears. This gives its face a look of ferocity and unrest.
