 Kzinti tails are naked and are similar in appearance to a rat's tail, and their noses are black.Kzinti ears have fur only on the outside of the ear and only about halfway up the ear itself, usually appear pink, and are shaped liked a segment of a Chinese parasol (or cocktail umbrella; they are also sometimes described as "bat-winged"); they can fold back flat against the head for protection during a fight.Kzinti speak in a hissing language called the "Hero's Tongue", which in its written form resembles commas and periods.
