I'm trying to figure out which is dominant from the pictures. I'm guessing the cat in the house. When we used to feed our ferals (there are only two left) they would have to wait turns to eat. There was a definite pecking order. And it was always the same. The more passive cats would wait off to the side until they had 'permission' to eat.

There was one cat that used to come. Not only was this cat submissive, but it was also tormented by birds (I think they were jays). Whenever the cat would come across the street the jays would swoop down as a group and chase it. He would have to take refuge under the front shrub. They never tormented any of the other cats. He must have disturbed their nest once and they never forgot.

Your cats are cute, but they do look cold :)
