This article discusses how the legal systems in several Western countries, with a special focus on Italy, address our present day animal rights movement and how these legal systems can faithfully reflect the movement’s values as well as promote them in a manner that will ultimately change the rights themselves and their cultural context: this is an extremely interesting issue for the semiotic study of the “humanization of animals”. Therefore, I will summarize several semiotic arguments using the model of the (...) four ontologies by Philippe Descola and the concept of prospectivism by Eduardo Viveiros De Castro. I expect several important changes will come about thanks to the ties between philosophical animal rights discourse and legal discourse and I also believe that the two most interesting issues will be animal labor and reproduction. I will concentrate on the debate over zoophilia laws in Denmark, Germany and Italy in order to propose a way to understand the threshold which separates humans and animals in our naturalistic ontology. Nowadays, “becoming animals” and “becoming humans” seem to be two central and open-ended semiotic processes: legal rights and animal rights philosophy help bring several issues into focus such as animal subjectivity and informed consent.
