I have no pets, and you can easily justify it. It is being fed, nutured and cared for, plus it was by selective breeding of past generations when we were hunters, that made them what they are today. On top of which the more people have pets, the less likely they produce in large number. 

How does that justify it exactly? I mean if you were to keep humans as pets but feed, nurture and care for them would that be ok?

Is the alternative that the human will be dropped off at a kill shelter or run over by a car?
