For those who may not be familiar with benefits of supplementing a diet with Essential/Omega Fatty Acids, here are two very good articles. "Omega fatty acids are in a class of dietary fats that have highly significant effects on the individual consuming them. They are composed primarily of carbon and hydrogen with a small amount of oxygen. Fatty acid requirements of felines are slightly different from the canine’s but both depend upon high quality fat sources in their diets. Over the past twenty years a tremendous amount of research on humans and animals have proven that Omega fatty acid intake in proper ratios and quantities effects a wide range of biochemical actions. Clotting factors, neurological development, cell membrane integrity and function, immune competence, energy generation and fat metabolism are just some of the metabolic activities directly affected by Omega fatty acids. Omega3 fatty acid, Omega6 fatty acid and Arachidonic acid are the three main fatty acids impacting the health status of dogs and cats. Dogs must eat Omega6 fatty acid in their food in order to survive; and from this single source the other two fatty acids can be created within the dog. Cats need both Omega6 fatty acid and Arachidonic acid and according to some nutritionists they even require an Omega3 fatty acid in their diet in order to survive."
