As of right now, our records indicate that NutriSource uses roughly 104 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 NutriSource, these are the most common ingredients found within the first 5 cat food ingredients.

  1. chicken
  2. chicken broth
  3. turkey
  4. pea
  5. natural flavor

As you can see, the most common first ingredient in NutriSource is chicken. The most common 2nd ingredient is chicken broth, followed by turkey, pea, and natural flavor.

Artificial Food Coloring Dyes

NutriSource does not use any artificial food coloring dyes. According to our records, none of the 12 NutriSource cat foods contain artificial food dyes.

Artificial food coloring dyes are unnecessary and potentially harmful ingredients. In general, we not not recommend feeding any pet foods that contain artificial dyes.

In 2010, the CSPI raised serious concerns regarding the safety of many artificial dyes. Most of the studies referenced by the CSPI involved prolonged or excessive consumption. Since most cats consume the same foods throughout their lives, concerns raised by the CSPI are alarming to say the least.

Animal By-Products

According to our records, NutriSource does not contain any animal by-products.

Animal by-products are basically the leftover parts of the the carcass after its been processed for meat. AAFCO defines by-products as the non-rendered, clean parts, other than meat, derived from slaughtered mammals.

Although by-products are still fairly nutritious ingredients, consumers have equated them with slaughterhouse waste. Therefore, most premium brands, including NutriSource have decided to remove by-products and instead use named organ meats (beef liver, chicken gizzards).

Anonymous Meat Ingredients

Anonymous meats are inexpensive low-quality ingredients that can come from practically any animal. These type of ingredients are often used to produce very inexpensive cat foods.

In general, we prefer ingredients which specify the animal source used to derive the ingredient. For example, ingredients such as duck fat are much better than animal fat or poultry fat.

In our analysis, we've looked through all 104 NutriSource ingredients. According to our data, NutriSource does not contain any anonymous animal-based ingredients.

Cereal Grains

Certain NutriSource 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.
