Perhaps it was option 2 or 3 originally which is why all the names are the same but over time transitioned into option 1 in a sort of abolition movement.
I could imagine the dairy and veal industry being a very sore subject for cows in zootopia, and casual references to dairy products might be a painful barb for them.
It is, but they retain the same names as dairy products did. If it was option 4, the cows in society would be separate from the milked creatures, so they might be totally unaffected by thinking about the dairy industry. It is unpleasant for different reasons, though
That’s what I’m saying. I’m interpreting “original names” to mean that they used to be made out of cow dairy products (instead of just happening on the same names we use), so option three is the only one where the cows in society might be totally unconnected to the dairy industry.
And those "lesser" chickens are created by injecting chickens after birth with something that makes them essentially mentally disabled, though they are still sentient
based on all the shit that cars 2 not only implies but explicitly shows on screen (genetically inferior racial underclass hell-bent on destruction of the civilised world, engine transphobia, sentient beings welded in place to do their work, force-feeding a man until his heart literally explodes out of his body, cartholicism), i would not at all be surprised if it turned out to be 3.
