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.
Are you considering feeding a raw diet to your kitten? Before you do, make sure you have the right information. Get the facts about 10 common myths associated with raw meat diets.
FACT: No scientific studies have shown benefits of feeding raw diets to kittens or cats. Their appeal is based on word of mouth, testimonials and perceived benefits.
FACT: Lynxes and other animals in the wild, like wolves, do eat raw meat (in addition to berries, plants, etc.). However, the average lifespan for an animal in the wild is only a few years. Therefore, what is nutritionally “optimal” for a wild animal like a lynx is not optimal for our pets that we hope will live longer and healthier lives.
FACT: Cats, especially kittens, senior cats or immunosuppressed animals, can become infected with Salmonella, Clostridium, Campylobacter and other bacteria found in raw meat diets, just as people can.
FACT: Even meats purchased at the best stores for people can contain harmful bacteria, so purchasing “human-grade” meat does not protect against the health risks of uncooked meats. (Ask yourself: Would you eat raw ground beef?) It is also important to keep in mind that the term “human grade” has no legal definition for pet food.
FACT: Most of the bacteria found in raw meat diets can easily survive freezing and freeze-drying.
FACT: Bones, whether raw or cooked, can fracture your kitten’s teeth. They also can block or tear the esophagus, stomach or intestine.
FACT: All the enzymes dogs and cats (and people) need for digestion are already in the gastrointestinal tract. Additional enzymes from food are not required for digestion.
FACT: Corn, oats, rice, barley and other grains are healthy ingredients that contain protein, vitamins and minerals; they are not added as fillers and are unlikely to cause allergies. Although meat is an important component of diets for kittens and cats, grains can be part of a high-quality, nutritionally balanced diet.
FACT: Byproducts are the animal parts American people don’t typically eat, such as livers, kidneys or lungs — in other words, the organs and meats other than animal muscle. Note that some pet foods may actually list these ingredients (e.g., duck liver, beef lung), but these are really just byproducts. Most commercial and many home-prepared raw diets also contain by products.
FACT: Most homemade (and even some commercial) raw meat diets are extremely deficient in calcium and a variety of other nutrients, even if chicken necks, bones or eggshells are added. This can be disastrous for any animal but especially for young, growing kittens, and can result in fractured bones. For complete and balanced nutrition, feed your cat a high-quality kitten food like IAMS™ ProActive Health™ Healthy Kitten.
