Pets are given loving names, like
pussinboots(or in my case, Tortoise, Achilles, etc.). They are unique, lovingly hand-raised, and cared for. You scale them up by making them bigger. And when they get sick, you nurse them back to health. Whereas cattle are given functional identification numbers like
vm0042. They are almost identical to each other. You scale them out by getting more of them. And when one gets sick, you replace it with another one.
