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.
If you are considering an all-natural, holistic, or organic kitten food, here are some facts you may not be aware of. Currently the pet food market is experiencing a push toward “all-natural,” “holistic,” and “organic,” the significance of which is still to be determined. The question becomes, is there an actual benefit to an “all-natural,” “holistic,” or “organic” diet?
AAFCO defines “natural” as “…derived solely from plant, animal, or mined sources… not containing any additives or processing aids that are chemically synthetic except in amounts as might occur unavoidably in good manufacturing practices.”
Loosely interpreted, this definition could include a range of “natural” products, including tobacco or any other naturally grown drug or substance.
None of these “all-natural” products are considered healthy additives for your kitten. So it is apparent that regulatory work is needed to define the true beneficial use of all-natural. Also noteworthy is the fact that nowhere within the definition are plant and animal by-products excluded. Not only are they “natural,” but they contribute valuable nutrients as ingredients in human and animal foods.
The term “holistic” kitten food is not distinctly defined by any of the regulatory agencies as a classification for food. This is particularly noteworthy in kitten food, because all diets sold commercially must be “Complete and Balanced” for a designated age or activity level. Or in other words, be a “holistic” dietary approach.
Organic kitten food is labeled “organic” by a government-approved certifier who inspects the farm where the food is grown to make sure the farmer is following all the rules necessary to meet USDA organic standards. Whether organic kitten food provides any additional safety or nutritional value is still being debated by experts. Even the USDA refuses to take a position. It is also important to note that there are no strict requirements for organic kitten food right now.
There is tremendous confusion surrounding the significance of all-natural, holistic, and organic kitten food terms. Widespread use without substantiation has forced several government and “watch-dog” consumer groups to become involved; this will result in more education and clarification as to what these terms really mean to consumers. But, for now usage of these terms requires your consideration.
