 The utilitarian position on animals, most commonly associated with Peter Singer and popularly, though erroneously, referred to as an animal rights position, is actually quite distinct. Here the moral significance of the claims of animals depends on what other morally significant competing claims might be in play in any given situation. While the equal interests of all morally considerable beings are considered equally, the practices in question may end up violating or frustrating some interests but would not be considered morally wrong if, when all equal interests are considered, more of these interests are satisfied than frustrated. For utilitarians like Singer, what matters are the strength and nature of interests, not whose interests these are. So, if the only options available in order to save the life of one morally considerable being is to cause harm, but not death, to another morally considerable being, then according to a utilitarian position, causing this harm may be morally justifiable. Similarly, if there are two courses of action, one which causes extreme amounts of suffering and ultimate death, and one which causes much less suffering and painless death, then the latter would be morally preferable to the former.
