Animal ethics, one of the most controversial topics of recent times, has produced a massive literature on animal rights. However, Will Kymlicka and Sue Donaldson believe that the animal rights movement has been stumbling for a while and needs a new path.  Thus, they wrote a book on Zoopolis: The Political Theory of Animal Rights to prevail over the question difficulty.  The proposed framework here for the solution is to extend the concepts of political philosophy such as agency, sovereignty, human supremacy, rationality, sentience, citizenship to the issue of animal rights. They aim to prove that a political theory which includes both positive and negative tasks can create fair conditions of the human-animal relationship. To be able to accomplish this task, they divide animals into three classes which correspond to three different political contexts: Domestic animals as citizens, wild animals as sovereign communities and liminal animals as denizens. Nevertheless, we will argue that Zoopolis itself is trapped in a "liminal" position between its own ideals and reality. Therefore, what Zoopolis lacks is an exact “decision” to get rid of staying in limbo.  Zoopolis, Animal rights, sovereignity, agency, citizenship, sentience, rationality.
