This is getting ...bad

Alright..So i thought we were making progress with Dutchy and her issue of going after LG, but shes taken a giant step back, and now has taken to seeking him out in the kitchen and if he twitches wrong she attacks him. Are there any suggestions on what I can do to introduce these two again? I have tried everything I know. She started doing this to him, after he was fixed. All the other cats in the house get alogn with him just fine. (bar jade because we have not worked on introductions yet with her..)

I am at my wits end here with Dutchys behavior. I am thinking perhaps its because of the kittens? She is being overly agressive and protective? They are 10 weeks old now...but..

anyone?

Not an expert but years ago, I had 4 adults...all females and all spayed. One of females used to go after another one of the females just after spaying. I believe it is a hierachy thing. Cats definitely have social structure and just maybe your female is going after your male to show him who's who around your house. These 2 females I had would really go at it. One day, the insanity and aggression just stopped. I guess they sorted out who was the Queen and who was not. How long has this been going on?

Been going on about 2 months or so now.....he knows shes the queen and he doesnt stand against her :/
