Your hypothetical makes little sense and is difficult to parse. It first supposes that there are any similarities or the moral sort between myself and livestock such that substituting one for the other is a comparison worth exploring. What if you put a slab of granite in that box? Or a helium balloon that yearns to be free? Can they suffer as well?
