It has become increasingly common for animal ethicists to advance deontological theories of animal rights, as opposed to merely welfarist theories of animals' moral significance. Kantians, however, have not been so quick to adapt. The gates to the Kingdom of Ends are closed to any who lack rational autonomy. Christine Korsgaard's recent work, however, has made a concerted effort to find a place for animals within Kant's Kingdom of Ends. I argue that Korsgaard can have animal rights or Kantian ethics, but not both.
