I've had a pair of siamese cats their entire life. They've been with us and together since they were kittens and they are related. I have NEVER had problems with them doing this. It seems like every time a baby comes over my S female acts aggressively to my N male. It has gotten pretty bad I have had to separate them this time. There is plenty of space for them to be apart but chloe just will not leave francis alone.. When there aren't kids around they bond and sleep/eat together. I'm worried about bringing a baby home of our own as we are trying. Anybody know what we should do? Getting rid of them is not an option as we consider them our first kids.
