“Domestic animals are neither a real or full part of our world or of the nonhuman world. They exist forever in a netherworld of vulnerability, dependent on us for everything and at risk of harm from an environment that they do not really understand. We have bred them to be compliant and servile, or to have characteristics that are actually harmful to them but are pleasing to us. We may make them happy in one sense, but the relationship can never be “natural” or “normal.” They do not belong stuck in our world irrespective of how well we treat them.”
All domestication is wrong. However, it is a good deed to save, adopt and foster an animal, from an animal shelter. We need to take care of them, since they are bred and raised in a way that they can’t survive in the wild.
Animals all deserve to live in freedom. Their purpose is not to be used by us. Their purpose is not to end up on our plate. Using animals,e.g. animal foods, disconnect us from our natural compassion and wisdom, and sense of being part of a benevolent universe.

Both domestication and eating animal products are two deeds that are hurting and using another sentient being, which is not ethical.
