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.
IAMS nutritionists were looking for a way to control hairball formation while maintaining optimal feline health and well-being. They evaluated risk factors for hairball formation in cats fed diets that varied in fiber source and content.
Researchers found that feeding diets that contained a blend of beet pulp and cellulose was more effective at moving hair through the digestive tract, compared with the same diets containing beet pulp as the only fiber source.
IAMS hairball formulas provide high-quality nutrition and taste, like our other adult formulas, with the added benefit of reducing the risk of hairballs.
