So my cat will stay by my side at all times, follow me every where and grab my feet and bite and grab them. Its kind of a love bite type bite but when I fuss her for it she turns so vicious.. then she is meaning to attack.. why is she doing this?! She will literally cry at my door when I throw her out room for being mean and when I can't take hearing her cry and let her back in she still comes in wanting my feet. If I sit still she is fine, it's when I walk to where ever.. she just started this a few weeks now so I haven't a clue.. any ideas!?
