> Maybe they just never develop a bond with these animals.

I love my chickens and I'm really sad when I lose some to predators. Yet I have no issue to harvest them for eating. They are not pets, I raise them for eggs and meat.

Maybe it's because I was raised on a farm, but I make a difference between pets and farm animals and that does not mean that I don't have a "bond" with some of the latter.

The first step is to acknowledge that there is something wrong here. This categorization of "pets" and "farm animals" as different sets is completely virtual. In real life, both are just animals.
