These are wild animals who are abducted and then chained to do forced labour. It doesn't sound like a happy life and if they had a choice in the matter, I doubt they would volunteer
All of the pets in your home wouldn't choose to live with you if they weren't conditioned to already. You would need to abduct them one way or another. They wouldn't volunteer to become food, either. Getting caught by another animal mean becoming food is the alternative to forced labor.
