Constitution. "Today, animal rights activists …" What are these "animal rights" people are always talking about? I'm not sure, but I think it's about our right to bark, peep and purr. And our right to bare claws, fangs and beaks, and to assemble in litters, packs and flocks. And our right to be secure in our dens and nests. And the right to avoid kangaroo courts, of course.
