You can bring in any can or bag of cat or dog food with artificial ingredients to Petco. You'll be able to trade that food in for a free, artificial-free upgrade to a select product that meets Petco's new nutrition standards.
Artificial ingredients include artificial colors, flavors and preservatives.
In a statement, Petco says it's the "first and only major retailer of pet food and treats to take a stand against artificial ingredients" by removing products that don't meet its standards.
