Do cats think of their owners as their slaves?

One time my cat (who is a girl so she’s very prim and proper) came and sat in front of me while i was on the couch and started looking from me to the bathroom so i went to the bathroom to see if anything was wrong. when i got in the bathroom she was standing in front of her litter box and started yowling at me (not a regular meow at all!) so i figured she wanted me to clean it, even though there was nothing in it. i told my friend about later that day and she told me about the whole cats thinking they’re rulers of the human race and everything.
