With regard to the various social protests, each time more numerous, against cultural practices that promote excessive abuse of animals or irrational beings, it resurges the controversial topic that from the legal philosophical raise the right that animals can get to have (Cardenas y Fajardo, 2007). Although from legal point of view the irrelevance of animal rights is based on the maximum: a) only rational beings are subjects of rights, b) the possibility of communication through language, from the philosophical is a need to ask questions about «equal living» (Ferrater y Terricabras, 1994) or the presence of a right that is common to both human beings as nonhumans, as is its existence. The reasons of those who defend or criticize the cultural practices that can lead to some kind of abuse in animals are beginning to have more importance for analysis at academic and cultural scenarios, to the point of transforming the legislation of the States as a reflex of a new ethic of sustainability in the context of global responsibility.
