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 impor¬tant 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 sup¬porting 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 composi¬tion 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 life¬style. 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.
Our cat food products contain animal-based proteins that provide all the essential amino acid requirements for cats. In addition, special refining and quality assurance tests ensure that we only use high-quality, highly digestible protein sources for increased digestibility.
Cats, best fed as true carnivores, require essential nutrients that aren't found in plant proteins such as soybean meal. For example, cats require taurine, which can only be found in animal-based proteins.
There are two important types of fatty acids for cats, omega-6 and omega-3 fatty acids. Omega-6 fatty acids, found in chicken fat and corn, are essential for maintenance of skin and coat and proper membrane structure. Omega-3 fatty acids are found in ingredients such as canola, fish meal or fish oil, and flax. Omega-3 fatty acids have been shown to be important in blood clotting and in managing inflammation, among other things. All of our products contain sources of omega-6 and omega-3 fatty acids.
IAMS™ research has shown that including omega-6 and omega-3 fatty acids in a ratio between 5:1 to 10:1 provides for optimal skin and coat condition in dogs. All of our products contain an adjusted omega-6:omega-3 fatty acid ratio between 5:1 to 10:1.
IAMS research has shown that moderately fermentable fiber, such as beet pulp, enhances intestinal health. The fermentable part of the fiber is broken down by intestinal bacteria to provide short-chain fatty acids, an energy source for intestinal cells. The non-fermentable component provides bulk for normal feces.
Using only highly fermentable fibers can cause problems, such as excess gas, while using only non-fermentable fibers, such as peanut hulls, promotes excess stool volume, because they are of no nutritional value.
All of our products, including IAMS ProActive Health™ Adult Original with Chicken, contain a patented fiber system of moderately fermentable fiber to help keep dogs’ and cats’ digestive systems healthy.
