They say that the eyes are the window to the soul. That is， simply looking into a person’s eyes can reveal details about what they are thinking and how they are feeling. In fact， in the animal kingdom， the eyes， and particularly the shape of the pupils， can actually tell us far more information about the animal. For example， some animals， such as cats and foxes， often have narrow， vertical pupils， while others， such as deer and sheep， have far wider and more horizontal ones. Such differences are， without doubt， no coincidence.
