Are you looking for high-quality food for your cat?

There are a lot of misleading words and messages on cat food packages. Getting the wrong food might lead to less optimal health outcomes in your cat.

In this article, I’m going to talk about how to read a cat food label. This will help you find the perfect cat food for your needs.

How To Read A Cat Food Label

Cat food labels are often misleading about whether they are good for your cat.

Reading a cat food label takes care and patience. There are state and federal laws that dictate the listing, naming, and use of ingredients.

My name is Derrick.  I write for Simply Cat Care, which is a site dedicated to helpful guides to understanding your cat.  I researched this topic to help you understand cat food labels. If you need more information on anything discussed in this article, seek the assistance of a veterinarian.

In this article, I’ll be going through the following topics:

Let’s get into the article.

The basics of reading a cat food label

Reading a cat food label is a difficult task. There are a lot of words, ingredients, and claims to sift through.

To read the labels of pet foods, you need to take your time with the individual product and work through each section.

Pet food manufacturers are bound by state and federal laws on the packaging. This stipulates what they can and can’t say on the package.

There are many ways to create statements that are legal but misleading or not in your best interest.

For your cat’s nutritional needs, you want to focus on selecting a high-quality product rich in essential nutrients that cats need for good health.

What is a guaranteed analysis?

This is a required analysis of the protein, fat, fiber, and moisture in pet food.

If a product says it contains 30% protein, that is the guaranteed minimum amount of protein in the protein by weight.

When the label says ‘crude’ protein or any other nutrient, that refers to the method of testing.

How do you read cat food calories?

Cat food labels must list the total kilocalories per kilogram of product.

They also provide a number of calories per household measure (e.g. per cup).

I wrote a cool guide to work out how many calories you need to feed your cat.

How does the ingredients list work on pet food labels?

The weight of each ingredient determines its order on pet food labels. This goes from highest to least weight.

The weight includes the moisture content of the individual ingredient.

Animal-based foods contain more moisture than dried grains (e.g. corn). This affects the interpretation, so be mindful of this.

Bottom Line: Ingredients are listed by highest to least weight.

Food label

How do you interpret the feeding guidelines?

Some products will list feeding guidelines for their product.

This will happen when a product claims to be a balanced food source for all or any particular life stage (e.g. kitten, adult cat, senior). The label will provide an amount of food per weight of the cat in this case.

For example, they might say a 4-5kg cat needs 40g of the food a day or 1/2 a cup. That is an example of a feeding guideline.

Bottom Line: A feeding guideline is a ballpark amount of food to give your cat optimal health.

How is cat food labeling regulated?

Regulation of pet food labeling happens at the federal level and the state level. That means the laws vary from state to state, and in different countries.

The United States Food and Drug Administration (FDA) enforces guidelines for general labeling in the USA.

Some states use the Association of American Feed Control Officials (AAFCO) guidelines for pet food labels.

The goal of the legislation is to give cat owners an informed choice about what they are feeding their cats. They are also there to protect them from harm.

Let’s review some terms used on cat food labels and what the laws state.

Bottom Line: The FDA enforces laws relating to what can go on cat food labels.

Serious looking meeting.

Product name

An ingredient used in a product name needs to comprise at least 95% of the total ingredients in the food (or 70% adjusting for water).

If there are two ingredients listed (e.g. lamb and mackerel) then the first listed name must have more of it in the food.

Descriptors get used if the ingredient listed on the product name is less than 95% of the food, but more than 25% (10% if including water).

A descriptor includes words such as:

  • Dinner
  • Nuggets
  • Platter
  • Entree
  • Formula

For example, if I made a cat food with 40% chicken, then I would have to call my food ‘chicken dinner’ or use another descriptor.

Similar to the 95% rules, if there are two ingredients with a descriptor the first ingredient must be higher in the product.

Another rule is the ‘with’ rule.

The with means the ingredient is 3% of the product weight. For example, a food that says Cat Food with Beef only needs 3% beef.

The word ‘flavor’ means only a trace amount of the ingredient needs detection.

Some examples of product names

Chicken Dinner (food must contain at least 25% chicken or 10% with moisture)

Mackerel Nuggets (food must contain at least 25% mackerel or 10% with moisture)

Lamb Cat Food (food must contain at least 95% lamb or 70% with moisture)

Cat Food with Salmon (food must contain at least 3% salmon)

Cat Food with Beef Flavor (only trace amount of beef needs detection)

Tuna and Chicken Cat Food (food must contain at least 95% tuna and chicken combined or 70% with moisture. The main ingredient must be tuna)

Choosing cat food in the supermarket.

Ingredient Statement

Ingredients on pet foods get ordered from top to bottom in terms of weight.

The ingredients must be generally recognized to be safe (GRAS). This means they cannot lead to any disorders or illnesses, based on research.

AAFCO provides guidelines for the nomenclature and proper naming of ingredients.

What is the AAFCO?

AAFCO stands for the Association of American Feed Control Officials.

This organization provides legislation recommendations for states. They do not directly control or endorse pet food labels.  

In other words, state legislation may use the guidelines provisioned by AAFCO or chose to use their own guidelines.

What is the FDA?

This stands for the United States Food and Drug Administration.

They stipulate guidelines for cat food labels in the USA.

Legal setting.

What are some misleading terms on cat food labels?

Let’s look at a few terms that cat food manufacturers use to try to sell their products.


Premium is a term that can mean anything. There is no law stating that manufacturers must abide by when making this statement.

Premium is a word to make products sound fancier.


AAFCO defines the term natural for state legislation guidance.

If a cat food claims to be natural, it must not include artificial flavors, colors, or artificial preservatives in the product.

Most cat food manufacturers do not use many of these things, except for artificial preservatives.

Natural is not a major factor in deciding the quality of the product and can mislead consumers into thinking the ingredients must be high quality.


Sometimes you will see an ingredient listed as a ‘meal’. For example, you might see chicken meal or beef meal. This can sound like a good ingredient because it’s an animal-based food, however, let’s take a closer look.

What does ‘meal’ mean (e.g. chicken meal)?

Meal: ‘Rendered product from mammal tissues, exclusive of any added blood, hair, horn, hide trimmings, manure, stomach, and rumen contents.’

As you can guess by this short description, a meal product is of lower quality than actual meat and organs (e.g. lamb liver).

In contrast, this is the definition of meat:

Meat: ‘Clean flesh of slaughtered mammals and is limited to…the striate muscle…with or without the accompanying and overlying fat and the portions of the skin, sinew, nerve and blood vessels which normally accompany the flesh.’

A meal is a lower-quality heat-treated product. It is better to focus on high-quality meat and organ-based foods.

Preparing meat.

How do you convert to a dry matter basis?

When looking at canned and dry cat food, you will notice there seems to be a higher percent quantity of protein and fat in dry food. This makes it seem like dry food is superior food.

The percentage of the total weight of the product includes moisture. The dry matter basis is the total percentage of the product minus the moisture.

For example, a product with 10% moisture has a 90% dry matter basis.

To make a fair comparison between canned and dry food, use an as-fed basis conversion.

How to calculate the as fed basis of cat food

Let’s look at a canned food and dry food example:

Dry food

30% crude protein

10% moisture (90% dry matter)

Canned food

7% crude protein

80% moisture (20% dry matter)

To find the actual as of the fed basis of protein, you need to use the following equation:

Protein/dry matter basis x 100

So for each example:

Dry food: 30/90 x 100 = 33%

Canned food: 7/20 x 100 = 35%

In this example, canned food is higher in protein when accounting for moisture.

One thing to keep in mind is moisture is an advantage to cat nutrition.

Cat’s have a difficult time drinking enough water to hydrate themselves when fed a dry food diet. Canned food provides water with food that is good for cats. Check out more awesome tips for cat nutrition over here.

What is the best cat food for your cat?

Cats are obligate carnivores and thrive off high-quality animal-based foods.

Many pet food manufacturers are not interested in what is best for your cat, but what is best for profit. This means using cheap ingredients and low-quality meat (e.g. chicken meal).

This also means finding ways of manipulating the system to trick cat owners (e.g. splitting one ingredient into multiple different names to seem like it appears less in the product). Many products add additional vitamins and minerals to account for the lack of nutritional quality.

The FDA does not require pet food to have pre-market approval. They simply require pet food to be deemed safe to eat.

Cat food with unlisted meat sources (e.g. poultry, meat meal) may contain many hidden meat sources. This may increase the risk of allergies from different protein sources.
