Sodium is an essential mineral for life. Found in the blood and in the fluid that surrounds cells, sodium maintains the cellular environment and prevents cells from swelling or dehydrating. Sodium is also important for maintaining proper nerve and muscle cell function.
Meat, poultry, fish, and eggs are good sources of sodium. It also may be included in commercial cat foods in the form of table salt (sometimes listed on the ingredient panel as salt). Salt is an important palatant for animals, as well as for people.
The Association of American Feed Control Officials recommends that dry cat foods contain at least 0.2% sodium for maintenance and to support normal growth and development. These are the minimum recommended levels.
While high sodium intake may cause increased thirst and water consumption, the extra sodium is excreted in cat urine.
Therefore, the sodium level in commercial pet foods is not a cause for concern in healthy animals.
A veterinarian may recommend decreasing a cat's sodium intake if the animal has some types of kidney, liver, or heart disease, in order to help decrease high blood pressure or the accumulation of excessive body fluid. Although older cats may be more likely to develop these diseases, healthy older cats do not require a low- or reduced-sodium diet.
The sodium level in our cat foods is appropriate for healthy cats. The sodium content in these foods is balanced in proper proportions with energy, other minerals, vitamins, fats, proteins, and carbohydrates.
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.
