Carpinteria, Calif.-based CKE Restaurants has agreed to improve animal welfare standards for products served at two of the company’s fast-food chains--Hardee's and Carl's Jr. The announcement follows a push from People for the Ethical Treatment of Animals. Under the agreement, 15 percent of all pork will be purchased from suppliers who do not confine animals in gestation crates. The company plans to increase that number to 25 percent by 2009.

"We take the animal welfare very seriously," says Jeff Mochal, a spokesman for Hardee's. “We want to stay consistent with where the industry is at now and where it's heading."

CKE Restaurants is not the first fast-food giant to make the change to sourcing cage-free animals. In March, Burger King announced that it would buy 10 percent of its pork from cage-free suppliers.
