11:FATS AND FATTY ACIDS
Dietary fats, mainly derived from animal fats and the seed oils of various plants, provide the most concentrated source of energy in the diet. Fats contain more than twice as much energy as protein and carbohydrates per gram. Dietary fats supply essential fatty acids that cannot be synthesized in the body and serve as carriers for important fat-soluble vitamins. Fatty acids play an important role in cell structure and function. Additionally, food fats tend to enhance the taste and texture of a cat’s food.
The maximum amount of fat in the cat’s diet can be reasonably high without any known adverse effects. In many cat foods, 50% or more of the energy comes from fat. Studies indicate that cat foods containing even higher amounts of fat are safe. At a minimum, cat foods should have a fat content of about 9% of dry matter.
Essential fatty acids are necessary to keep your cat’s skin and coat healthy. Deficiencies in the so-called omega-3 family of essential fatty acids can lead to a host abnormalities of the nervous system, ranging from vision problems to impaired learning ability. Another family of essential fatty acids, known as omega-6, has been shown to have important physiological effects in the body. Tissues that perform such functions as storage (fat), metabolism (liver), mechanical work (muscle), and excretion (kidney) tend to have cell membranes in which omega-6 fatty acids predominate.
12:VITAMINS
Vitamins are organic compounds that take part in a wide range of metabolic activities. Vitamin deficiencies can cause a variety of health problems. Cats cannot synthesize some vitamins from precursors (pre-vitamin structures) in the diet. For example, they must get all of the vitamin A and niacin they need directly from the food they eat. Deficiencies in vitamin A can adversely affect the health of the eyes. Adult cats deprived of niacin in the diet will lose weight and may die as a result. The diets fed to many cats, especially canned food containing fat-laden fish products, make them more susceptible to deficiencies of certain vitamins, such as vitamin E. Vitamin E, an antioxidant, provides protection against oxidative damage. Some vitamins are not only essential in small doses, but are also toxic in excess amounts. Too much vitamin A, a natural consequence of feeding large amounts of liver to growing kittens, can cause hypervitaminosis A, a condition characterized by a variety of skeletal lesions.

13:MINERALS
Twelve minerals are known to be essential nutrients for cats. Calcium and phosphorus are crucial to strong bones and teeth. Cats need other minerals, such as magnesium, potassium, and sodium, for nerve impulse transmission, muscle
contraction, and cell signaling. Many minerals that are present only in minute amounts in the body, including selenium, copper, and molybdenum, act as helpers in a wide variety of enzymatic reactions. The requirements for certain minerals may change as your cat ages.
Cats can get too much or too little of a specific mineral in their diets. An excess of dietary magnesium, for instance, has been implicated in the formation of stones in the urinary tract. Foods that maintain relatively low urinary pH levels, however, have been shown to prevent these stones.
