Every kitten food has protein, but here are some important facts about the different types of protein to help you choose the right food for your kitten. It is important to remember that the source of protein is vitally important to kittens because one of the principle nutritional philosophies is that kittens are best fed as carnivores.
Some pertinent facts when listening to the claims and advertising of various manufacturers:
1. Recommended kitten food protein levels are established by nutrition experts from around the world and published as NRCs (Nutrient Reference Charts). These protein requirement levels are determined by meeting the animal’s need for essential amino acids, the building blocks of protein; and by monitoring/calculating the nitrogen balance (a comparison between the intake of nitrogen in the diet and the losses through urine, feces, and evaporation from the skin and mouth). Nitrogen balance has been the recognized method of determining protein requirements for many decades. Variations in levels from what has been established for many years should be validated by convincing research. If the change in level isn’t backed by supporting evidence of a tangible benefit, then there may be hazards. Studies in several species have found a link between diets with high protein levels (greater than 40% protein), bone loss, and urinary tract stones.
2. Protein from plant sources may elevate the amount of protein, but may not be as beneficial as animal-based sources of protein in kitten food because of lower digestibility, effects on muscle-to-fat body composition ratio, and the range of amino acids they provide.
3. There are only three sources of energy in any kitten food diet–fat, protein, and carbohydrate (starch). If the amount of one element is raised, the amount of one or two of the others must be lowered to maintain a proper energy level in the food for your kitten’s life stage and lifestyle. A balance of nutrients is important to your kitten because each of the nutrient groups supplies something very specific for the kitten’s body. Excess protein above your kitten’s actual needs cannot be stored for future use and will be converted into fat.
Corn is found in many cat foods — but not all corn is created equal. Learn more about this ingredient, its forms and its role as a source of energy for your cat.
Corn is included in cat food formulas in various forms, such as ground corn, corn meal, corn grits, corn gluten meal and corn bran. When reviewing the ingredients list on cat food packaging, you may see one or more of the following corn ingredients:
Corn Ingredient | What It Is |
Ground corn or corn meal | Finely ground and chopped whole corn |
Corn grits | The portion of ground corn containing little or none of the bran (fiber) or germ (the small protein portion at the end of the kernel) |
Corn bran | The outer coating of the corn kernel; largely fiber |
Corn gluten meal | A dried protein source that remains after the corn’s bran has been separated and removed and a large portion of the carbohydrate and germ have been removed |
Corn is included in the formulas for all IAMS cat foods, including IAMS™ ProActive Health™ Healthy Adult and ProActive Health™ Healthy Kitten. It is more appropriate to associate the corn used in our products with “corn bread” rather than “corn on the cob.” The difference is similar to cooked corn versus raw corn. We use only the highest-quality corn in our products. The corn is finely ground to a meal, which breaks up the outside covering of each kernel, and then it is cooked, which increases its digestibility.
Corn grits and corn meal are used in our foods as high-quality sources of carbohydrates, which are an important source of energy. Corn generally also results in lower glycemic and insulin response than rice. This can be especially beneficial for senior and overweight cats.
