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.
If you are considering an all-natural, holistic, or organic kitten food, here are some facts you may not be aware of. Currently the pet food market is experiencing a push toward “all-natural,” “holistic,” and “organic,” the significance of which is still to be determined. The question becomes, is there an actual benefit to an “all-natural,” “holistic,” or “organic” diet?
AAFCO defines “natural” as “…derived solely from plant, animal, or mined sources… not containing any additives or processing aids that are chemically synthetic except in amounts as might occur unavoidably in good manufacturing practices.”
Loosely interpreted, this definition could include a range of “natural” products, including tobacco or any other naturally grown drug or substance.
None of these “all-natural” products are considered healthy additives for your kitten. So it is apparent that regulatory work is needed to define the true beneficial use of all-natural. Also noteworthy is the fact that nowhere within the definition are plant and animal by-products excluded. Not only are they “natural,” but they contribute valuable nutrients as ingredients in human and animal foods.
The term “holistic” kitten food is not distinctly defined by any of the regulatory agencies as a classification for food. This is particularly noteworthy in kitten food, because all diets sold commercially must be “Complete and Balanced” for a designated age or activity level. Or in other words, be a “holistic” dietary approach.
Organic kitten food is labeled “organic” by a government-approved certifier who inspects the farm where the food is grown to make sure the farmer is following all the rules necessary to meet USDA organic standards. Whether organic kitten food provides any additional safety or nutritional value is still being debated by experts. Even the USDA refuses to take a position. It is also important to note that there are no strict requirements for organic kitten food right now.
There is tremendous confusion surrounding the significance of all-natural, holistic, and organic kitten food terms. Widespread use without substantiation has forced several government and “watch-dog” consumer groups to become involved; this will result in more education and clarification as to what these terms really mean to consumers. But, for now usage of these terms requires your consideration.
