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.
Why should cat food have sodium in it? Sodium content in cat food has an important nutritional and dietary function, just like it does in your food! But it’s important to understand just what it does and how much of it is healthy. That way you can make the best possible decisions about what to feed your cat.
Sodium is an essential mineral for life. Inside the body it is found in the blood and in the fluid that surrounds cells. Sodium itself helps ensure proper nerve and muscle cell functions, maintains a healthy cellular environment and prevents cells from swelling or dehydrating. The sodium levels in IAMS™ cat foods are balanced with other minerals, vitamins, fats, proteins and carbohydrates. That way you can be sure your cat is getting enough for their health.
Meat, poultry, fish and eggs are all good natural sources of sodium, and are the primary ingredients in all IAMS™ cat foods including IAMS™ PROACTIVE HEALTH™ Healthy Adult.
Sodium may also be included in commercial cat foods in the form of ordinary table salt. Salt is an important ingredient in making food more palatable for animals, as well as for people.
The Association of American Feed Control Officials recommends that dry cat foods contain at least a minimum of 0.2%1 sodium — 0.2% of dry matter your cat eats, or 0.5 grams per 1,000 kcal — for maintenance and to support normal growth and development. While higher sodium intake may cause increased thirst, water consumption and urination, excess sodium is passed in the urine.
A veterinarian may recommend changing your cat’s sodium intake to help decrease high blood pressure, eliminate excessive body fluid or as a precaution if kidney, liver or heart heath is a concern. You can keep track of your cat’s overall wellbeing at home if you regularly check their C.A.T.S. — Coat, Appetite, Temperament and Size — for any changes that might lead to questions for the vet.
Healthy cats of all ages don’t normally require a low- or reduced-sodium diet, so be sure to talk to your vet about any sodium concerns you may have before making a change.
Cats’ bodies work differently from our own, and learning to care for them is a process! What your cat eats impacts everything from their energy levels to their mood to the health of their skin and coat. By understanding what healthy cats and kittens need from their food, like sodium, antioxidants, fiber and more, you’re better able to give your cat a diet that helps them thrive.
