From my experience, once this behavior starts it is hard to stop. It is unusual that it is happening with two spayed sisters. I have two sisters that really get into it when one is in heat. They only fight in my presence so I really think it is a jealously thing. I do hope you can get help. My only advise is that until you can get it resolved you might need to setup an x-pen and put the aggressive one in timeout until she cools off. Have you tried pulling some coins in a can and shaking a can when they start fighting. Sometimes that will stop them. |
