CKE Restaurants will be buying cage-free pork for two of its fast-food chains -- Hardee's and Carl's Jr. This is in response to pressure the People of the Ethical Treatment of Animals.

According to the agreement, CKE will purchase 15 percent of all pork from suppliers who do not use gestation-sow crates. The company plans to increase that number to 25 percent by 2009.

"We take the animal welfare very seriously," Jeff Mochal, a spokesman for Hardee's, told the Associated Press. "When you meet with PETA, they make a pretty good case. We want to stay consistent with where the industry is at now and where it's heading."

CKE Restaurants follows Burger King in making this change. In March, Burger King officials announced that the company would buy 10 percent of its pork from suppliers that forego gestation-sow crates.
