Reply #6: my cats fuss at each other sometimes.

[RainDog]

I have a male and female who didn't start out together but who have lived together for a decade. They have areas of domiance in the house... If one cat is lying on my bed, the other will sit at the door until the other leaves. but they can stand side by side and drink and eat. they startled me the other day when I realized one of them was at one end of the couch and one at the other.

but they also play at fighting. they'll hide and jump out at each other sometimes (the calico does this to the tabby more - she's younger, too.)

I got another kitten that had been abandoned and, when I did, the younger cat, the calico, would not come near me for months. when a kid came over her, the kitten got out and I didn't know about it. the last I heard of her, she had followed some deer down the overgrown gullyway behind houses. I went everywhere looking for her... that was so hard.

After a month or so the calico became friendly again.

maybe they're re-establishing territory, too?
