I think we enslave them, and that most people do it with no real thought, like most slave owners before abolition. And I think it is demonstrated along the whole spectrum from being a living productive tool at one end (to provide eggs or meat at least cost possible) to being a living doll (including being doted on and dressed up in cute outfits) at the other.
And as slaves did, some get a reasonably good life from this; most don't; and very few have any say in what happens to them, any freedom to do what they want to do instead of what their owner wants them to do. And in return they impose constraints on their owner.
Having pushed the big red button

let's lighten the mood (and prod the brain) with another Diogenes anecdote: (note, ancient Greece was a slave society, based not on colour, but on being a loser in one domain or another). "And he bore being sold with a most magnanimous spirit. For as he was sailing to Ægina, and was taken prisoner by some pirates, under the command of Scirpalus, he was carried off to Crete and sold; and when the crier asked him what art he understood, he said, “That of governing men.” And presently pointing out a Corinthian, very carefully dressed, (the same Xeniades whom we have mentioned before), he said, “Sell me to that man; for he wants a master.” Accordingly Xeniades bought him and carried him away to Corinth; and then he made him tutor of his sons, and committed to him the entire management of his house. And he behaved himself in every affair in such a manner, that Xeniades, when looking over his property, said, “A good genius has come into my house.” Diogenes Laertius, Lives of the Eminent Philosophers, Diogenes the Cynic IX
