Yeah, it is pretty remarkable. I consider it non controversial at this point that many of humans favorite meals are certainly capable of a lot of suffering.

I think that was never a real question. Lobsters might or might not feel pain, okay, but bovines and other mammals certainly do. And birds are (can be) pretty intelligent (eg parrots).

So that's why they are supposed to be kept, raised and slaughtered in relatively humane conditions. (Eg. free range, and painless death.)
