In my experience, cats always sort of assume that they are in charge and I don't believe that I've ever seen a cat who didn't think itself dominate over it's owners. You can see evidence of it's assumed superiority in it's behaviors. For example, when a cat rubs against you it's leaving it's own unique scent and pheremones on you so other animals know that you belong to it. Also, they feel that you aren't able to care for yourself when they bring you dead animals (food) so they must think themselves more competent than you! Another good way to tell if they are dominate over you is to check their litter box. Cats who don't bury their feces are basically advertising that there's nothing in the area that can take them on (Cats bury feces to avoid predators and to not challenge more dominate cats).
