In traditional Western view, then, we own nonhuman animals nothing.We have no moral obligations to them.We may have moral obligations concerning them, but those obligations are to other people.We ought not, for example, poison somebody else’s pet, for the same reason that we ought not destroy somebody else’s sofa.The pet and the sofa are another person’s property, and our obligations to that person forbid us to destroy his property.The pet itself is due no more moral consideration than the sofa - none.
