How Do We Know What Animals Are Really Feeling?

That morning in the banquet room, the academics and experts who organize the contest (under the sponsorship of the American Veterinary Medical Association, the nation’s primary professional society for vets) laid out three different fictional scenarios, each one involving a binary choice: Which animals are better off?

Another involved bison being raised for meat, some in a smaller, more managed operation and others ranging more widely with less hands-on human contact.
