Cat food labels provide limited information regarding the nutritional value of the package contents. It is important for customers to know what can and cannot be determined from the label, and what information is particularly important. Major components of a pet food label include:
Values in the guaranteed analysis are expressed as either minimum or maximum. A maximum guarantee (% max) means at most this specific amount of the nutrient is included in the formula. A minimum guarantee (% min) means at least this specific amount of the nutrient is included in the formula. The following four nutrients must be included on all pet food labels:
For example, a cat food with a 25% minimum crude protein guarantee should contain at least 25% protein, but could contain much more. The only way to determine the actual amount is by laboratory analysis.
Other information may be guaranteed on cat food products, such as magnesium (% max), taurine (% min), ash (% max), and linoleic acid (% min).
Ingredients must be listed in order of abundance (largest quantity listed first).
AAFCO nutritional adequacy statements are required on all pet foods. Products may either be formulated or tested according to AAFCO procedures and recommendations.
Veterinary-exclusive products include statements such as, 'This product is intended for intermittent feeding only' and 'Use only as directed by your veterinarian.'
Manufacturing codes allow the company to track products for quality and inventory issues. In order to quickly and efficiently handle a customer inquiry, the company's customer service department will usually ask the customer for this code.
Expiration or 'Best Used By' dates are optional, but are helpful in determining product freshness and shelf life.
The manufacturer's information should include the company name, address, and phone number so customers can quickly and easily obtain product information.
A toll-free telephone number should be provided as a convenience to the customer and to ensure that a charge is not incurred when calling for information.
Before you assume that by-products in kitten food are a bad thing, here are some facts. In common usage, a by-product is something that is just that—a side product from the making of another product. By-products are not by definition poor quality. For instance, gingerbread cookies wouldn’t be the same without molasses, which is a by-product of sugar manufacture.
In relation to IAMS™ kitten and cat foods, by-products are generally parts of the animals that are not the muscle meat preferred by most consumers. The term refers only to the anatomic parts included, not to the nutritional quality of the parts.
While many may not be used to eating these animal parts themselves, it is important to realize that many of the items included in by-products (e.g., organ meats) may be higher in essential nutrients—amino acids, minerals, and vitamins—as well as more palatable to pets than the skeletal muscle meat.
In addition to nutritional benefits, inclusion of these ingredients in pet foods reduces waste and likely has environmental benefits as the livestock industry does not have to produce additional animals just to satisfy the needs for muscle meats to feed pets as well as people. Feeding these nutrient-rich, tasty parts to pets may prevent them from being wasted.
Much of the consumer confusion and discomfort surrounding by-products most likely stems from the marketing strategies of some pet food brands and perhaps from the ingredient name “by-product” itself.
It is important to keep in mind that most ingredients in pet foods can vary greatly in quality. In addition, quality cannot be assessed purely on the basis of the ingredient list. All by-products are not the same quality. Neither is all muscle meat. There are very high-quality by-products as well as poor-quality chicken and chicken meal.
Purchasing food only from reputable manufacturers who are very selective about their suppliers, have full-time, qualified nutritionists, and perform analytical testing to ensure that every ingredient, as well as the finished product, meets their exact nutrient specifications, will help avoid problems due to poor-quality ingredients.
