A horse LadyDina aquired on a trip into Wonderland with PrincessDeirdre, HorseCavallo is an Akhal-Teke, a "...most unusual breed of riding horse, highly regarded for its speed, stamina, comfortable gaits, intelligence and trainability."

Cavallo can be tempermental, a trait of his breed. "...Akhal-Tekes often bond closely with their human partners; they are usually sensitive to the way they are treated. Responsive to gentle training, they can be stubborn and resentful if treated rudely."
