That gets kind of into a complicated overlap of human and animal behaviour. One the one hand you have what the animal is normally exposed to in their environment, but still would have to figure out if that is what they actually want, if possible (i.e. some aspects of living in the wild they might like more, and other aspects of domesticated living they may prefer). On the other hand, should the whole of animal behaviour be used as a model for human behaviour? Just because that is how animals normally do things doesn't necessarily mean it is the most preferred, and humans usually have more options, like choosing not to do such acts or not to kill some animals for food, and still surviving.
