BEEFTINK, it has been my experience with female felines, that once the pattern has set in of these two females not liking each other, that there is little that can be done, to cause them to live together in harmony. May I suggest that you either permanently separate them, such as re-homing the one,and keeping the other, or if your facilities allow, that you keep one as an outside furkid, while the other (the most adaptable to inside living) stays inside.
