Crude Protein Comparison For Cat Food
Cats require twenty-two amino acids to sustain life. Eleven of these amino acids are synthesized naturally, the remaining eleven are consumed. Protein is the nutrient which provides some or all of these eleven essential amino acids.
If you look at the average percentages of crude protein, you'll notice that Whiskas typically guarantees 3.56% more protein. This is a fairly small difference between Whiskas and Diamond, but still worth mentioning. In addition, Whiskas wet cat foods also provide more protein than Diamond wet foods.
Crude Fat Comparison For Cat Food
There are many ways in which dietary fat contributes to the overall health of our feline friends. Here is a short list of benefits provided by fats (not exhaustive):
Help transport nutrients across cell membranes
Fats produce metabolites, which help control inflammation
Maintain healthy blood pressure
Slow the growth of yeast infections
Fats improve the taste/texture of food.
According to our data, Diamond guarantees 3.90% more fat than Whiskas. Although this difference is relatively small, it's still a notable difference. In addition, Diamond wet cat foods also provide more fat than Whiskas wet foods.
As you can see, Whiskas and Diamond guarantee a similar amount of crude fiber. For wet cat foods, Whiskas provides significantly more fiber (about 13.81% more).
Whiskas Pet Food Ingredients vs. Diamond Pet Food Ingredients
Whiskas and Diamond both use the following controversial ingredients in many of their products:
Brewers Rice
Brewers Rice
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.
Corn Gluten Meal
Corn Gluten Meal
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.
Poultry By-Product Meal
Poultry By-Product Meal
Poultry by-product meal is a controversial ingredient because the source animal is not specified. Anonymous ingredients such as poultry by-product meal are typically low-quality ingredients in comparison to named protein by-product meals (e.g. chicken by-product meal, turkey by-product meal, duck by-product meal).
Here are some of the controversial ingredients used only by Whiskas.
Liver
Liver
Liver is a controversial ingredient because the source animal is not specified. Anonymous animal ingredients are typically very low quality and may contain almost any animal, including dogs and cats!
Iron Oxide
Iron Oxide
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.
Ground Wheat
Ground Wheat
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.
Wheat Gluten
Wheat Gluten
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.
Caramel Color
Caramel Color
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.
Ground Yellow Corn
Ground Yellow Corn
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.
Here are some of the controversial ingredients used only by Diamond.
Meat Meal
Meat Meal
Meat meal is produced by cooking meat using a process called rendering. The rendering process dramatically reduces the natural moisture of meat and thereby results in a highly condensed protein source.
This ingredient is marked controversial because the source animal for the meat is not specified. These type of anonymous ingredient are typically very low quality and certainly inexpensive additions. The most unpleasing property of this ingredient is that the meat source can contain any mammal, even dogs & cats.
White Rice
White Rice
White rice is produced by removing the husk, germ, and bran of rice grains. Unlike brown rice which contains the bran and germ, white rice is nutritionally empty.
Ground Corn

Tomato Pomace
Tomato Pomace
Tomato pomace is a by-product of tomato manufacturing. It's considered a controversial ingredient because many people believe it is an inexpensive low quality filler. However, tomato pomace provides a notable amount of dietary fiber, B vitamins, Lycopene, and vitamin A. Although it is a very inexpensive ingredient, it is not nutritionally empty.
Beef By-Products
Beef By-Products
By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, beef by-products contain nearly all parts of the beef 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, beef 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 beef by-products, supply many important nutrients required by pets.
Powdered Cellulose
Powdered Cellulose
Powdered cellulose is produced from minuscule pieces of wood pulp and plant fibers. Other than its fiber content, powdered cellulose lacks any nutritional contribution.
Chicken By-Product Meal
Chicken By-Product Meal
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."

Ground Whole Grain Corn
Ground Whole Grain Corn
Ground whole grain corn contains 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 pet food.
Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.

Canola Oil (Preserved With Mixed Tocopherols)
Canola Oil (Preserved With Mixed Tocopherols)
Canola oil is a plant-derived oil from the seeds of canola plants. Although fat is an essential component of any diet, canola oil is controversial in pet food. Proponents claim that canola oil provides a better fat profile in comparison to other plant based oils. However, opponents claim that canola oil is typically produced with genetically modified rapeseed and that rapeseed oil has multiple adverse health affects.
We believe that certain pet food ingredients are linked to adverse health affects; these ingredients are classified as harmful.
Here are some of the harmful ingredients used only by Whiskas.
Bha
Bha
Butylated hydroxyanisole (BHA) is an artificial preservative and possible cancer-causing agent. Studies have show that BHA can be linked to various tumors in laboratory animals.
Bha/Bht
Bha/Bht
Butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are both artificial preservatives. According to the World Health Organization, BHA and BHT are both possible carcinogens.
Animal Fat (Preserved With Bha And Citric Acid)
Animal Fat (Preserved With Bha And Citric Acid)
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. What's more, this ingredient is preserved with BHA, an artificial preservative and possible carcinogen according to the World Health Organization.
Here are some of the harmful ingredients used only by Diamond.
Menadione Sodium Bisulfite
Menadione Sodium Bisulfite
Menadione sodium bisulfite is a synthetic version of vitamin K that has been linked to many health concerns. Research has suggested possible toxic reactions in liver cells and red blood cells among other serious problems. In fact, one large chemical supplier warns, "The substance is toxic to kidneys, lungs, liver, mucous membranes. Repeated or prolonged exposure to the substance can produce target organs damage."
