This is a picture of Kit and Kat. They are Twins, and they live in Holland. Kit is the boy, and Kat is the girl. Of course their real names are not Kit and Kat at all. Their real names are Christopher and Katrina. But you can see for yourself that such long names as that would never in the world fit such a short pair of Twins. So the Twins' Mother, Vrouw Vedder, said, "They cannot be called Christopher and Katrina until they are four and a half feet high."
