I feed mine Innova EVO RM (supplemented with raw). Mine were really gassy when I first moved them onto it too but it seemed to get better during the second bag of it. Natura pet foods has decided to purchase or build their own canning facility in the future to ensure the quality of their foods. There's a video at http://www.naturapetcare.com/ about their products and new steps they are taking right now to ensure the continuing safety of their foods.
