not short for anything. The advantages are:
      a.  the boys will like it.
      b.  the girls will soon accept it.
      c.  the teachers will get used to it.
      d.  combining it with a middle name makes it more appealing, especially when paired with other gender-benders, i.e., Kit Morgan, Kit Tyler, Kit Cassidy, or a very feminine version would be Kit Delicata. (See Delicata)

Kit is usually a nickname for Catherine for girls and Christopher for boys. It is sometimes used on its own.
