Meow Mix vs. Purina Cat Chow

Pea protein is produced by removing the starchy parts of peas. Pea protein is considered controversial because it provides a substantial plant based protein boost. This boost is undesirable because plant based protein is typically lower in biological value when compared to meat based proteins.

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.

Ground wheat is regarded as an inexpensive and low-quality filler in pet food. However, wheat does provide plant-based protein and makes pet food more affordable for consumers. It's important to note that plant based protein does not provide the same amino acid profile as meat based protein.

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.

Soybean hulls are a by-product of soybean oil and meal processing. They are typically regarded as low quality and inexpensive fillers which lack any significant nutritional value.

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.

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 pet food.

Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.

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.

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 pets to sustain life. Therefore substituting corn for meat is an unsuitable substitution and actually degrades the overall protein quality of the product.

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 pet food should certainly warrant further questioning.

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

Turkey by-product meal is produced by cooking turkey 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, turkey by-products contain nearly all parts of turkeys which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.

Like other meat by-products, turkey 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 "named" by-products, such as turkey by-products, supply many important nutrients required by pets.

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."

Corn syrup is made from corn starch and it's typically used as a thickener, sweetener, and humectant (keeps the product moist). It's considered controversial because it can raise a pet's blood sugar to unhealthy levels. Of course this concern may be nullified if the syrup is used in very small quantities.

Iron oxide is an FDA approved natural food coloring agent. It's commonly found in rusting metal and provides a reddish-brown color.

We believe food colorants are unnecessary ingredients in pet food. Other than potential harm, food colorants do not provide any nutritional value. These type of ingredients are used only to make the food look appealing to humans.

Fat product is controversial because the source of the fat is not identified. Ingredients which do not clearly specific a source are typically very low quality ingredients.

Whole wheat is one type of whole grain and contains the entire grain of wheat (the germ, bran, and endosperm). Wheat is regarded as an inexpensive and low-quality filler in pet food. However, wheat does provide plant-based protein and makes pet food more affordable for consumers. It's important to note that plant based protein does not provide the same amino acid profile as meat based protein.

Poultry meal is a controversial ingredient because the source animal is not specified. Anonymous ingredients such as poultry meal are typically low-quality ingredients in comparison to named protein meals (e.g. chicken meal, turkey meal, duck meal).

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.

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!

Caramel color is a concentrated form of caramel, a natural food colorant. Caramel color has been linked to cancer in laboratory animals. Since our pets do not care about food color, caramel color is an unnecessary addition with possible health risks.

Specific vegetable oils are typically positive ingredients; however, this ingredient does not specify which vegetable(s) were used to produce the oil.

Without this information, it is impossible for us to make any specific statements. With any fat source, it is important to know the omega-3 to omega-6 fatty acid ratio, a property which cannot be determined with this ingredient. Thus, we have marked vegetable oil as a controversial ingredient.

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.

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.
