Natural Balance Green Pea and Duck Formula Dry Cat Food is a limited ingredient, grain free product. The food is made for both kittens and adult cats. It does not have any artificial flavors or colors. It is a highly digestible cat food that meets the nutritional guidelines established by the AAFCO. Also, Natural Balance has a program where you can get one free bag of this cat food for every same sized 12 bags you purchase. You do have to cut out and turn in the UPC codes and fill out a simple information envelope (to place the UPC codes in) that asks for your name, address, where you bought the product and dates. Since I have five cats and feed four feral cats from my neighborhood, this program is very helpful to me. Quality of Ingredients The ingredient list for this dry food is simple, limited and very good quality. Other than added vitamins and minerals, the ingredient list is as follows: peas, duck, duck meal, pea protein, canola oil, flaxseed, and natural flavor. My cats will eat this but do prefer the Natural Balance Green Pea and Chicken Formula better. I use the duck formula to change things up since they do seem to tire of eating the same foods, day in and day out. Flavor Selection This dry food comes in three flavor formulations, Green Pea and Duck, Green Pea and Chicken, & Green Pea and Salmon. This is one of several foods that I feed my cats on a regular basis. I only feed my kitties grain free dry food with no by-products or artificial ingredients. My cats and I are very pleased with this food.
