In the English version, Sissy came after Willy because she wanted to teach him a lesson and also settle a score with him for tormenting her at the beginning of the film. In the original version of the film, Sissy saw Willy as a meal, since cats eats sparrows, and seemingly became the film's primary antagonist when she was intent on eating her owner while he was in sparrow form. In the English version, the scene when Sissy is about to devour Willy is cut off and rushed to the part when Willy's sister Tonya comes in and stops Sissy from eating him, possibly because it might frighten the younger audience.
