People generally don't care about non-moral agents. Say children and other animals. They are treated as "property" in society; things that are "owned" and claimed to have no rights until they reach an age they can be independent. Are there philosophies in which non-moral agents are valued and have rights like moral agents are claimed to have?

Are there philosophies in which non-moral agents have the same rights as moral agents?
