Topsie is a little, four years old cat, who becomes an agent at the O.W.C.A. She is Perrys best friend and always happy and friendly. Another (best?) friend of Topsie is Tilly, she is a cat too. Tilly is VERY plumb and very nerved when Topsie tells her storys or when she dosn´t let her sleep. Topsie talks often and can be very LOUD. She is a pretty active cat.
