The Humane Society and religious leaders have teamed up to raise awareness about how animals are raised for food.

“We are urging people of faith to take a small step in their daily lives by switching to cage-free eggs or egg substitutes during the month of October as an act of compassion for farm animals,” said Wayne Pacelle, president and CEO of the Humane Society of the United States, in a Wednesday announcement.

Among religious leaders joining the cause is the Right Rev. John Bryson Chane, the Episcopal bishop of Washington, D.C., who said the “All Creatures Great and Small” campaign fits with “the religious spirit that compels us to show them our mercy and regard.”
