Is there any way you can confine the cat to a small room where it's hard for her to escape? Many people on here wouldn't agree with this, but I've had very good luck taming cats by gently "forcing" contact. I have a treat in one hand, and use the other to hold the cat gently but firmly. I have found that if they can hear my heartbeat they calm down some. Or you can try the go slow and bribe 'em approach! Either way, it's best if you go one on one without other kitties around to be "buttinski's".
