Hi and welcome to PetTalk! It is probably just a fun game for her and she knows it is naughty so she runs away quickly! You may want to run some water in the bathtub or sink and see if she is interested in getting her feet wet . . . it has been known to happen, although I've personally never had the good fortune to have a cat that was interested in water sports. I guess it can be messy, so . . . maybe I'm not missing too much . . .
