They took the cousin who remembers. Can you imagine these animals feeling that way , It would be sad, since we feed on them, and when they're born, even if their mothers take care of them, the end of their lives is literally dinner. I'd rather not even think about it 😔
Animals eat animals too. They say pigs are intelligent. I doubt they think this way and if it comes to the moms they feel it if the piglets are takem away but there's also a moment they push them away and don't want to take care of them and siblings forget they are related.
