Freedom I see you also have 7 cats, like me. 2 live with my mom. anyway I just read my post , I guess I should give their names so its less confusing.

at my house, the 3 females are Daisy, Emily and Rose. The males are Oreo (he's black and white) and Snickers. (guess I was hungry when I named them lol!)

Oreo and Snickers were kittens together. Emily and Daisy are littermates and are the ones that protected the kittens from another cat not living with me now. Emily and Rose have always been equal, sometimes Emily would chase Rose away other times Rose would chase her away, rivals for attention. it was never a big deal, the females usually all get along, which I always thougth odd because I thought females are more territorial.
after the male kittens grew up, Emily would be bossy or mean with them if they went around her for whatever reason. Snickers is still scared of her and will keep his distance, but Oreo is the one that got mad that time. He is tame with all the other cats, he will play with his brother sometimes and they are still close like Daisy and Emily. Rose and Oreo are also close. If I could divide them, if I had a bigger house or 2 stories, I would put Emily and Daisy together and then Rose, Snickers and Oreo together.
