After meeting up with Crystal, Ashlee examined the kittens, who were approximately three weeks old. The little cats were covered in fleas and were in very poor condition.What you mean when you say that you 'treated them for fleas and worms' is that you poisoned the fleas and the worms. In other words, we found in nature three sets of animals struggling to survive, chose one of them, and destroyed the other two for the benefit of the one.
“They were just skin and bones – completely emaciated,” Ashlee recalled. “I immediately treated them for fleas and worms and then took them home. I fed them and gave them a nice warm place to sleep.”
What's the justification for that? We feel perfectly justified in doing it because we like cats (very much) more than fleas and worms. We certainly have the power to do it, so if power is its own justification -- might makes right -- then our aesthetic preferences coupled with our power are enough.
Religious folks like myself can appeal to Genesis 1, of course, but that's not going to serve as a legal justification under a regime that does not allow for the establishment of religion.
Will the EPA someday prevent us from picking up kittens and "treating" them for fleas and worms? If not, why not? Just because the aesthetic preference is so common?
