Purina Pro Plan Cat Food Ingredients

Purina Pro Plan Logo

Purina Pro Plan manufactures roughly 118 different cat food products. Each product utilizes a unique set of ingredients to achieve a desired nutritional profile.

In this article, we'll explore Purina Pro Plan ingredients and answer many of the most common questions.

As of right now, our records indicate that Purina Pro Plan uses roughly 173 different ingredients.

First 5 Ingredients

Cat food ingredients in the United States are listed in descending order of pre-cooked weight. The first 5 ingredients typically constitute a significant portion of the recipe.

For Purina Pro Plan, these are the most common ingredients found within the first 5 cat food ingredients.

  1. water sufficient for processing
  2. liver
  3. liver
  4. wheat gluten
  5. meat by-products

As you can see, the most common first ingredient in Purina Pro Plan is water sufficient for processing. The most common 2nd ingredient is liver, followed by liver, wheat gluten, and meat by-products.

Artificial Food Coloring Dyes

Our records indicate that Purina Pro Plan does use artificial food coloring dyes. More specifically, we've identified 2 artificial food dyes used by Purina Pro Plan.

Although these food dyes are classified as Generally Recognized As Safe (GRAS) by the FDA, we recommend avoiding them when possible.

According to the Center For Research In The Public Interest (CSPI), there are many potential health risks associated with the consumption of artificial food coloring dyes.

Given that most pets consume the same products for prolonged periods of time, these concerns should be taken seriously. In general, we recommend pet owners avoid feeding products which contain artificial food coloring dyes.

For more information regarding the CSPI's findings, read our artificial food coloring article.

red 3
2 Recipes

Red 3 is an artificial dye which the FDA has confirmed can cause cancer in laboratory animals.

The following recipes contain red 3:

added color
47 Recipes

The ingredient "added color" is ambiguous and may include various artificial dyes. Most artificial dyes have been linked to various chronic diseases.

The following recipes contain added color:

Animal By-Products

Purina Pro Plan does indeed use animal by-products. More specifically, 5 animal by-product ingredients were found during our analysis of Purina Pro Plan cat food ingredients.

According to AAFCO, by-products are defined as the non-rendered, clean parts, other than meat, derived from slaughtered mammals. In other words, animal by-products are the leftover ingredients that humans typically do not consume (lung, heart, tongue, stomach, intestine, blood, etc).

Many consumers have equated animal by-products with slaughterhouse waste. Animal by-products are still very controversial. Most premium brands have abandoned them in favor of specific named organ ingredients (duck liver, chicken heart, etc).

If you must feed a product with animal by-products, ensure that the specific animal source is specified. In other words, avoid ingredients such as meat by-products or poultry by-products.

meat by-products
82 Recipes

By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, meat by-products contain nearly all parts of the animal which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.</p><p>This ingredient is marked controversial because the meat source is not identified. Anonymous ingredients such as meat by-products are typically very low quality additions. The most unpleasing property of this ingredient is that the animal source can contain any mammal, even dogs & cats.

The following recipes contain meat by-products:

poultry by-products
4 Recipes

By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, poultry by-products contain nearly all parts of poultry which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.</p><p>Like other meat by-products, poultry by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste. However, manufactures and many experts claim that animal by-products are unjustly criticized. Proponents state that by-products, such as poultry by-products, supply many important nutrients required by cats. Finally, we must also note that this ingredient is considered an anonymous meat ingredient because the specific type of poultry is not specified. By-products which are "named", such as chicken by-products are typically higher in quality when compared to the more general poultry by-products.

The following recipes contain poultry by-products:

chicken by-product meal
2 Recipes

Chicken by-product meal is produced by cooking chicken by-products using a process called rendering. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, chicken by-products contain nearly all parts of chickens which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.</p><p>Like other meat by-products, chicken by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste.

The following recipes contain chicken by-products:

Anonymous Meat Ingredients

Anonymous meats are animal-based ingredients which do not provide the source animal's name. These ingredients are controversial because they can come from almost any animal.

In addition, anonymous animal-based ingredients are very inexpensive and often the lowest quality meats that are still allowed to be used in pet food.

In general, we do not recommend feeding any products which contain anonymous meats. When in doubt, always contact the brand's customer service desk for further clarification.

Unfortunately, we've identified 12 anonymous meat ingredients used by Purina Pro Plan.

fish meal
17 Recipes

Fish meal is defined by AAFCO as "the clean, dried, ground tissue of undecomposed whole fish or fish cutting, either or both, with or without the extraction of part of the oil." Since the specific type of fish is not mentioned, we cannot discuss any specific qualities of this ingredient. In general, anonymous ingredients are low quality inclusions when compared to ingredients such as tuna meal, salmon meal, catfish meal, etc.

The following recipes contain fish meal:

animal fat (preserved with mixed tocopherols)
26 Recipes

Animal fat is a by-product of tissue rendering. The source animal is not specific and therefore we cannot be certain that the source does not include diseased animals or even euthanized dogs and cats.

The following recipes contain animal fat (preserved with mixed tocopherols):

poultry liver
2 Recipes

Organ meats like poultry liver are an excellent source of protein, fat, and essential vitamins and minerals. Although organs may not sound appealing, organs are an important component of a carnivorous animal's diet.</p><p>Unfortunately, poultry liver is considered an anonymous meat because the specific type of poultry is not specified.

The following recipes contain poultry liver:

ocean fish
3 Recipes

Ocean fish can refer to multiple species of fish, since the particular type of fish is not specified, it's difficult to discuss this ingredient. The nutritional contribution of ocean fish depends on the species included; however, fish generally provides high quality protein and fat.

The following recipes contain ocean fish:

meat by-products

Anonymous ingredients such as meat by-products are typically very low quality additions. The most unpleasing property of this ingredient is that the animal source can contain any mammal, even dogs & cats.

The following recipes contain meat by-products:

animal digest
2 Recipes

Animal digest is the result of undecomposed animal tissue after hydrolysis, a chemical reaction. It is typically used as flavoring to improve taste. Animal digest is considered by many as an undesirable low-quality ingredient. What's more, the source animal is not specified and therefore animal digest can contain almost any animal, including dogs and cats!

The following recipes contain animal digest:

poultry by-products
4 Recipes

By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, poultry by-products contain nearly all parts of poultry which are typically not consumed by humans.

The following recipes contain poultry by-products:

poultry giblets
2 Recipes

Poultry giblets includes the heart, liver, gizzards, and other internal organs of poultry. Organs are nutritiously dense ingredients which provide high quality protein and fat. However, this particular ingredient is considered an anonymous meat ingredient because the type of poultry is not specified. In order words, "named" giblets such as chicken giblets or turkey giblets are preferred over poultry giblets.

The following recipes contain poultry giblets:

Cereal Grains

Certain Purina Pro Plan cat food recipes contain one or more grains. The specific ingredients are listed below.

For cats, we typically recommend choosing a grain-free recipe. Cats are obligate carnivores and therefore grains are not species appropriate.

The kibble production requires a binding agent. Grains are commonly used for this purpose in cat food. When purchasing grain-free cat food, grains are often replaced with another starchy source. This is also not ideal.

To avoid grains and other starchy additions, consider feeding wet or frozen recipes.

long grain rice
1 Recipes

Long grain rice is a gluten-free carbohydrate source. As long as the bran and germ of the grain are intact, rice can provide a notable amount of fiber and nutrition. However, because the type of rice ("brown" or "white") is not specified, we cannot make this determination.

The following recipes contain long grain rice:

whole barley
1 Recipes

Whole barley is a nutritious carbohydrate source. It's a great source of dietary fiber, B vitamins, magnesium, manganese, phosphorus, and zinc.

The following recipes contain whole barley:

wheat flour
18 Recipes

Wheat flour is produced by grinding uncooked wheat into a powder. In addition to dietary fiber, wheat flour provides various vitamins, minerals, and plant based protein.</p><p>Wheat is considered a controversial ingredient because of it's protein content. Plant based proteins degrade the overall protein quality in the product. In addition, many people believe wheat is one of the most common ingredients to cause food allergies or intolerance. However, grains such as wheat are typically low offenders in comparison to certain protein sources such as beef.

The following recipes contain wheat flour:

barley
1 Recipes

Barley is a nutritious carbohydrate source, naturally rich in dietary fiber and various minerals. Unlike pearled barley, regular barley contains the entire grain.

The following recipes contain barley:

modified corn starch
32 Recipes

Modified corn starch is derived from the endosperm of the corn kernel. The modified term indicates that the corn starch has been treated or processed in order to expose or improve some property. Typically, corn starch is used as a binder in kibble.

The following recipes contain modified corn starch:

corn bran
1 Recipes
corn gluten meal
24 Recipes

Corn gluten meal is a by-product from the production of various corn products (corn starch, corn syrup, etc). It's very high in protein (nearly 60% protein) and therefore can significant boost the protein content of the product. Because plant based proteins such as corn gluten meal are inferior to meat based proteins (lack many essential amino acids), they are not suitable substitutes.

The following recipes contain corn gluten meal:

brewers rice
21 Recipes

Brewer's rice is the small fragments of rice kernel that are separated from the larger kernels of milled rice. The fragments do not contain the same nutrition profile of the whole kernel and therefore brewer's rice is a lower quality grain. Brewer's rice is typically regarded as an inexpensive and low quality filler.

The following recipes contain brewers rice:

wheat gluten
47 Recipes

Wheat gluten is the main protein of wheat. Although wheat gluten is mostly protein, wheat gluten is considered controversial because it significantly boosts the protein content of the product. This is undesirable because plant based protein does not provide the same amino acid profile as meat based protein.

The following recipes contain wheat gluten:

brown rice
2 Recipes

Brown rice is naturally rich in fiber and various minerals including manganese, phosphorus, and magnesium. Relative to other grains, brown rice is easy to digest.

The following recipes contain brown rice:

wild rice
2 Recipes

Wild rice is a gluten-free grain which supplies protein, dietary fiber, certain minerals, and B vitamins.

The following recipes contain wild rice:

whole grain corn
3 Recipes

Whole grain corn is the entire corn kernel (the germ, bran, and endosperm). Corn is a cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in cat food.</p><p>Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.</p><p>Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.</p><p>In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked. In regards to the protein contribution, we must note that corn is a plant based protein which does not contain all of the necessary amino acids required by cats to sustain life. Therefore substituting corn for meat is an unsuitable substitution and actually degrades the overall protein quality of the product.</p><p>Finally, we'll discuss the claims about vitamins and minerals in corn. Although corn does provide many vitamins and minerals, it not necessarily an exceptional ingredient in this regards. There are many other ingredients which are more complete and biologically appropriate. Therefore the usage of corn as the primary ingredient in cat food should certainly warrant further questioning.

The following recipes contain whole grain corn:

ground yellow corn
2 Recipes

Ground yellow corn is a cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in cat food.</p><p>Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.</p><p>Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.</p><p>In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked.

The following recipes contain ground yellow corn:

corn oil
7 Recipes

Corn oil is extracted from the germ of corn kernels. It contains an omega-6 to omega-3 fatty acid ratio of 49:1. Corn oil's unfavorable omega-6 to omega-3 fatty acid ratio makes it an undesirable ingredient. Consumption of such ingredients can lead to an array of health problems in both animals and humans.

The following recipes contain corn oil:

oatmeal
1 Recipes

Oatmeal is simply coarsely ground oats and therefore contains the entire oat grain. As with regular oats, oatmeal is rich in dietary fiber, B vitamins, and various minerals.

The following recipes contain oatmeal:

rice
22 Recipes

Rice is a gluten-free carbohydrate source. As long as the bran and germ of the grain are intact, rice can provide a notable amount of fiber and nutrition. However, because the type of rice ("brown" or "white") is not specified, we cannot make this determination.

The following recipes contain rice:

rice starch
1 Recipes

Rice starch is a gluten free carbohydrate derived from rice. Typically, rice starch is used as a binder in kibble.

The following recipes contain rice starch:

Controversial Ingredients

In most cases, ingredients which are given the controversial classification can be substituted with higher-quality alternatives. You should evaluate each controversial ingredient independently to see if there is truly a valid cause for concern.

Keep in mind, certain sacrifices often must be made to produce cat foods at a reasonable price. In general, the more expensive the product, the fewer controversial ingredients you'll find.

In our analysis, we've identified 24 controversial ingredients inside Purina Pro Plan products. These controversial ingredients are listed below. Click on each ingredient for more information.

canola meal
3 Recipes

Canola meal is a high protein by-product of canola oil production. This ingredient is marked controversial because it may be derived from genetically modified rapeseed, which is associated with multiple adverse health affects.

The following recipes contain canola meal:

soybean flour
21 Recipes

Soybean flour contains more than 50% protein. Therefore, soybean can significantly boost the protein content of the product. The inclusion of non-meat protein typically degrades the overall quality of protein in the recipe. This degradation is due to the inferior amino acid profile of plant based proteins.

The following recipes contain soybean flour:

soybean protein concentrate
34 Recipes

Soybean protein concentrate is produced by removing the water soluble carbohydrates from soybeans. The inclusion of non-meat protein typically degrades the overall quality of protein in the recipe. This degradation is due to the inferior amino acid profile of plant based proteins.

The following recipes contain soybean protein concentrate:

powdered cellulose
18 Recipes

Powdered cellulose is produced from minuscule pieces of wood pulp and plant fibers. Other than its fiber content, powdered cellulose lacks any nutritional contribution.

The following recipes contain powdered cellulose:

animal fat (preserved with mixed tocopherols)
26 Recipes

Animal fat is a by-product of tissue rendering. The source animal is not specific and therefore we cannot be certain that the source does not include diseased animals or even euthanized dogs and cats.
