We can hardly speak of moral in relation to creatures we systematically devour, mostly singed but sometimes raw. There are men and women who practise horse love, dog love, cat love, bird love. But these very people would take a deer or a calf by it's neck, slit it's throat, drink the blood straight away or in a pudding, and bite off it's flesh. And who is to say that a horse they cherish is nobler that a deer they feed on? Indeed, there are people who eat cats, dogs and horses but would use a cow only as a work animal and the dogs to protect them and their properties.
