Katie you should try to rehome her to a family that only wants one cat sometimes the issues go away once they are in an environment that only contains one cat? I have found that on a purebred cat website that a ton of the time it has to do with stress and being with all your babies might just be to much for her? Might be a win win??? I totally know how you feel my dear, I wouldn't have dealt with it this long. I would have taken her to a rescue group or found someone to take her. SO sorry for you and Suzie this will be difficult but you do have to do whats best for your family.... Prayers that the medication suggestion works. I will be thinking of you both.
