The worst of it is even legal for cats and dogs, too: selective breeding to the detriment of health. It’s not our right to breed a dog to have difficulty breathing and hip dysplasia for our own desires, and neither is it right to breed a cow to be in pain when not milked by a human (then ensure the cow is constantly lactating). Same thing with a chicken laying a pretty large egg almost every day. I personally believe there’s no pasture big enough to right that wrong.
