Even more unpopular, let people do what they want. Some people consider their pets a big part of their life, and love them even more than they do people. And just like we do with sick people that would probably be better off being put down, we try to keep them alive and give them the best possible life. It’s selfish, I know. But you have no right to tell anyone what they should or shouldn’t do about the life of their loved ones. And that includes pets.
