Choosing the right food for your feline companion can feel overwhelming with all the marketing claims on the front of the bag or can. However, the most important information is always found on the back or side panel. Here is a step-by-step guide to decoding a cat food label so you can make the best nutritional choice for your pet.

1. The Product Name and the “95% Rule”

The words in the product name are heavily regulated and give you a good idea of the primary ingredients:

• “Chicken Cat Food” or “Beef Entrée”: By AAFCO (Association of American Feed Control Officials) regulations, the named ingredient must make up at least 95% of the total product (or 70% if including water for processing).
• “Chicken Dinner,” “Formula,” or “Platter”: The named ingredient must make up at least 25% of the product.
• “With Chicken”: The named ingredient only needs to make up at least 3% of the product.
• “Chicken Flavor”: The product must simply taste like chicken, usually achieved through additives, and can contain less than 3% of the actual ingredient.

2. The Ingredient List

Ingredients are listed in descending order by weight, before they are cooked. Because cooking removes a lot of moisture, keep the following in mind:

• Meat First: Look for a specific named animal protein (e.g., “chicken,” “salmon,” or ” lamb”) as the first one or two ingredients. Avoid foods where grains or plant proteins top the list.
• Whole Meats vs. By-Products: Whole meats contain a lot of water weight, which can push them higher up the list. By-products (such as organ meats) are actually very nutritious for cats, provided they come from named animal sources (e.g., “chicken by-products” rather than generic “meat by-products”).
• Watch for Splitting: Some manufacturers list different forms of an ingredient (e.g., corn flour, ground corn, corn gluten meal) separately so they appear lower on the list, even though the total amount of corn is quite high.

3. The Guaranteed Analysis

This section provides the minimum or maximum percentages of four key nutrients:

• Crude Protein (Minimum): Cats are obligate carnivores and need high levels of protein. Look for high percentages, especially in dry food (often 30% to 40%+).
• Crude Fat (Minimum): Fat provides essential fatty acids and energy. Typical adult cat foods range from 9% to 20% fat.
• Crude Fiber (Maximum): This measures indigestible plant matter. Most cat foods contain 1% to 5% fiber, which aids in digestion and hairball control.
• Moisture (Maximum): Canned or wet foods usually contain around 75% to 78% moisture, while dry foods contain around 10%. Keep in mind that you cannot directly compare protein and fat percentages between dry and wet food without converting them to a “dry matter basis” because of the difference in moisture.

4. The AAFCO Nutritional Adequacy Statement

This is arguably the most important sentence on the label. It tells you whether the food is nutritionally complete and balanced, and for which life stage:

• “Animal feeding tests using AAFCO procedures substantiate that [Brand] provides complete and balanced nutrition for…”: This means the food has actually been tested by feeding it to live animals. This is the gold standard.
• “[Brand] is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for…”: This means the food was formulated in a lab to meet nutrient guidelines, but has not necessarily undergone live feeding trials.
• Life Stages: Look to see if the food is formulated for “growth and reproduction” (kittens and pregnant/nursing queens), “maintenance” (adult cats), or “all life stages.”

5. Feeding Guidelines

The back of the package will include a chart suggesting how much to feed based on your cat’s weight. Remember that these are just starting points. Every cat has a different metabolism and activity level, so you may need to adjust the portion size to help your cat maintain an ideal body condition.

By taking a few extra minutes to read past the front-of-package marketing and examining the ingredient list, guaranteed analysis, and AAFCO statement, you can ensure your cat is getting the high-quality nutrition they need to live a long, healthy life.
