The clear difference is the fact that I think most normal people can clearly agree that, bringing excess harm to any animal for no greater reason, is wrong since most people do live with household pets they wouldn't want harmed.

Many would oppose what's done to pigs if it were done to dogs, and even if you wanna say its "about intelligence", its not like people wouldn't see harm towards cats as 'fine'.

For a more quantitative argument like what >>5016574 wants, I can't imagine that CAFOs are anything close to sanitary safe meat no matter what they tell you.
