My problem has never been the girls. It has always been the boys. Tex could be aggressive, and Monte is totally aggressive.

Kirsten, I wonder what goes on during the day. Could you use a tape recorder and see if there is anything? If it is true that it is only when you are home, then, I am thinking of something Cesar Milan says/does with dogs.

When Lilly stalks, and you intervene, you are "rewarding" her with attention- your attention. How do you break things up? Clap? Use some other sound device? Do you go to Luna, and comfort her?
