At the Institute the directors have noticed there is a pecking order. The subjects sometimes have trouble with their interpersonal relationships. Velvet is at the top of the pecking order and often instigates fusses with all the subjects of the Institute, even with her play buddy Socks. Zippy is next in the pecking order in that she often chases Rebecca and Citikitty, but she never gets into a real cat fight any subjects.
Poor Citikitty, the youngest at the Institute and the lowest on the pecking order, has mapped out hidey holes where she can get away from bully Velvet and irritant Zippy.
