Chicken is a key ingredient in IAMS™ cat food. Its protein can help maintain healthy muscle structure, and it naturally provides each of the amino acids essential to carnivorous animals. And chicken adds great taste.
Another common chicken-based ingredient is natural chicken flavor, also called chicken digest. Natural chicken flavor adds palatability and nutrients. It is high-quality protein and fat material that has been reduced to amino and fatty acids to improve taste through an enzymatic process.
Internal organs are a rich source of protein, fats, and minerals, such as iron, that are essential to cat health and they add a taste that cats enjoy. Including some ground bone provides a good source of minerals, such as calcium. Some pet food manufacturers formulate their products without such ingredients to appeal to cat owners, rather than for the health of the cats themselves. However, the nutritional needs of cats are not the same as those of humans.
Dried (meal) chicken protein sources contained in our chicken-based cat foods, such as IAMS ProActive Health™ Adult Original with Chicken , undergo an extra refining process and contain each of the amino acids that are essential to cats.
Linoleic acid, a naturally occurring omega-6 fatty acid found in common pet-food ingredients such as corn and chicken fat, is a required nutritional component of the canine and feline diet.
Fatty acids are the building blocks of dietary fat and are formed by specific combinations of carbon, hydrogen, and oxygen.
Certain groups of fatty acids, called omega-3 (fatty acids in which the first double bond is located at the third carbon atom) and omega-6 (fatty acids in which the first double bond is at the sixth carbon atom), are particularly important to various functions in the cat's body.
The first double bond is located at the sixth carbon atom and, therefore, is an omega-6 fatty acid.
Omega-6 fatty acids are essential for maintenance of skin and coat condition, normal growth, proper membrane structure, and absorption of fat-soluble vitamins.
Linoleic acid is the most important omega-6 fatty acid because it cannot be synthesized by cats, and it is used to make other omega-6 fatty acids.
Cats also require arachidonic acid, because they cannot synthesize it from linoleic acid.
Most pet foods contain more than the required amount of linoleic acid. However, IAMS research shows that it is not just the amount, but the ratio of omega-6 to omega-3 fatty acids, that is most beneficial to cats.
The optimal omega-6:omega-3 fatty acid ratio to maintain a healthy skin and coat in dogs and cats is between 5:1 and 10:1, so five to 10 omega-6 fatty acids should be present for every one omega-3 fatty acid.
