There's a bit more difference between animals and humans than their is another intelligent race with better technology.
That's why I didn't single out technology as the only benchmark for human superiority.
But to answer your question, they'd certainly have the right to try.
This answer avoids the whole point of the question. Assuming they could easily succeed in dismembering and boiling you alive to make you a little tastier, or force you to haul a haul freight like an ox, or make you perform circus tricks, would there be any reason for them to consider your feelings? Can they be judged at all for treating you like livestock?
