She requires the blood of another Kat to survive, as like all Vampires she can only feed on blood. Blood of another animal will only keep her strong for an hour, whereas the blood of a Kat will keep her going for 24hrs. Her eyes are sky blue, a major mutation for Vampires - they're only supposed to have red eyes. She also has a bit of red fur at the back of her neck, this is another mutation but a minor one.
