I didn't have time, to read all the posts at the bottom, but in my opinion, the people, who consider themselfs, "owners" are the same people who consider they "own" their wife or girlfriend, as in, domestic abuse. They have to have "control" over something, an animal or women too afraid to fight back.
My kitties are my babies, I care for them, as a mother would care for a child, who is unable to care for his/her self, so in that respect, I am their mother.
I also don't actaully care, what anybody thinks, of what I call myself. To them, I say, take your best shot, you will not win.
