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.
Compared to humans, your cat needs a high-fat, high-protein diet along with other important nutrients. Cats usually eat many small meals throughout the day, so they easily adopt a free choice feeding schedule to maintain their normal body weight. Dry foods, such as IAMS™ PROACTIVE HEALTH™ Healthy Adult with Chicken, are best suited for free choice feeding because they stay fresh for a longer period.

Here are few tips on how to feed a cat:
Wondering what do cats eat ? Cats need nutrients from animal-based protein sources. Providing the vitamins, minerals, proteins, and other components found in a portion of complete and balanced pet food can help your cat live a long and healthy life. It is important to avoid supplementing your cat's diet, as doing so may lead to a variety of health problems.
When selecting cat food, refer to a cat nutrition chart that offers the following nutrients:



Same time, we recommend you control the amount of food you feed your cat. Even if it is a weight loss-based cat food, the quantity should be checked properly.
The amount to feed your cat depends on its age, size, and activity level. Feeding guidelines that recommend the daily amount of food you may feed your cat are included on all IAMS packages. Start feeding your cat the mentioned amount and adjust according to its needs. Remember to divide the portion accordingly if you feed more than once a day. With that said now, take a look at this chart on how much to feed a cat:
| Weight of cat (kg) | G/day |
|---|---|
| 3 | 45 |
| 4 | 55 |
| 5 | 60 |
| 6 | 70 |
| 7 | 80 |
| 8 | 90 |
