Good nutrition is as important to your cat as it is to you, but her nutritional needs are quite different! Unlike humans, a cat needs a high-fat diet with less fibre. Even if you prefer a vegetarian diet, you should understand that cats are carnivores. They need nutrients from animal protein and fat for optimal health, and they benefit from fibre for a healthy digestive tract and carbohydrates for energy.
With thousands of pet foods available, how do you pick the one that's right for your cat?
Start by identifying the cat's life stage and lifestyle. Kittens, nursing mothers, and mature/senior pets are examples of life stages, and each has different nutritional requirements. All cat foods should state which life stage they are recommended for.
Nutritional needs also vary depending on lifestyle. A cat whose primary activity is guarding the couch doesn't need as much energy as one who likes to spend time roaming outside.
Finally, it is important to take into account any special medical condition your cat may have, including food allergies that might require a special diet recommended by your veterinarian.
Once you've determined your cat's life stage and lifestyle needs, decide whether to feed dry or wet food. Most cats thrive on only dry food. This type of food promotes oral hygiene and health through abrasive action. Some cats, especially finicky eaters, enjoy the smooth and wet texture of canned or pouch foods.
Remember that, while dry food can be left in a bowl all day, wet food should be thrown away after 30 minutes if not eaten. Dry food is the best choice for busy people who are not normally home during the day.
Once you know your pet's nutritional needs and your pet's preference, you are ready to go shopping.
Because cats need the nutrients found in animal sources, it’s best to pick a food in which a primary ingredient (one of the first ones listed) is an animal-based protein source such as chicken, lamb, fish, egg, or one of their by-products. These ingredients contain all the essential amino acids, including taurine, which isn’t found in a vegetable-based protein source.
Using a combination of carbohydrates in a diet, such as corn meal or barley and grain sorghum, ensures efficient absorption and helps maintain energy levels. And beet pulp is an excellent fibre source that promotes a healthy digestive tract.
For a soft, thick coat and healthy skin, your pet needs fatty acids like those found in vitamin-rich fish oils and quality fat sources such as chicken.
Cat food labels provide limited information on the nutritional value of your pet's food because labeling regulations do not allow manufacturers to describe the quality of ingredients on the package. A reputable pet food manufacturer can explain to you how they evaluate and assure the quality of their products.
When choosing food, the price on the bag, while important, is usually not the best consideration. A low price may indicate cheap ingredients, or ingredients that change as manufacturer costs fluctuate.
In addition, many lower-priced products have higher daily portions to provide the same amount of nutrition found in a high-quality diet. To get a better idea of cost, it is the cost per feeding, not the total cost, that counts.
To figure cost per feeding, divide the total cost by the number of days the product lasts. For example, a 20-lb bag of food that costs $18.99 and lasts 30 days is $0.63 per day. A 20-lb bag that costs $15.99 and lasts 20 days costs $0.80 per day. When compared closely, high-quality pet foods are quite favourable to other brands.
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.
