"It's harder to eat meat when you know the animal's name," Jon Stewart, who recently adopted his own pigs, confessed on "The Daily Show" Monday night.
"They're not different than cats and dogs, in terms of their desire to be friends with us," interviewee Gene Baur, co-founder of Farm Sanctuary, added. His sanctuaries take rescue animals from factory farms and allow people to meet the animals in person.
