It always surprises me how humans collectively “mechanize” nature, so it’s easier to rationalize exploiting it.
If cattle benefitted from domesticating humans and could pull it off, they would do so with pride.
Is this equally true to you?

The cat might eat your dead body because it's trying to avoid starvation (after all, your ghost presumably isn't continuing to feed it, and it's stuck inside with your corpse and doesn't know how to use your cellphone to call for help), just like humans did in the Andes mountains, as seen in the movie "Alive". There's nothing immoral about eating a dead animal to survive.
So “FYI” yes they do.
Similarly, my stomach produces stomach acid, my sweat glands produce sweat, etc., and none of that is "mechanized" or used for any kind of industry, it's just how my (and your) body works.
