In spring 2012, after losing the main source of funding for its Enviropig project, the University of Guelph killed its last remaining Enviropigs. Or, as a university spokesperson put it, the pigs were "humanely euthanized." Through an engagement with this particular case, I examine the ethical implications of using the term euthanasia to describe the killing of perfectly healthy animals who were bred for research but are no longer needed for this purpose. Given the ethical shortcut that terms like euthanasia (...) provide, I call on research institutions, and the institutions that regulate them, to attempt to justify the killing of these animals without recourse to such terms.
