Summary

IAMS Adult Tuna is a dry cat food formulated for adult cats aged 1 year and older, designed to support overall health through high animal protein content and targeted functional ingredients.
The first ingredient is dried chicken and turkey (39%), with chicken making up 24%, providing a highly digestible and biologically appropriate source of animal protein to support lean muscle maintenance and daily energy needs.
With a total crude protein content of 35% and 88% of that protein derived from animal sources, the formula emphasizes species-appropriate nutrition that aligns with a cat’s natural carnivorous diet.
Dried tuna (4%) adds variety to the protein profile and contributes additional omega-3 fatty acids, which support skin health and coat shine.
The inclusion of pork fat and fish oil provides essential fatty acids, including 0.28% omega-3 and 2.7% omega-6, which help maintain a healthy skin barrier and glossy coat.
Taurine is present at 0.19%, a critical amino acid for cats that supports heart muscle function and vision health.
A tailored fiber blend, including 1.8% dried beet pulp and 0.73% fructooligosaccharides (FOS), promotes digestive health by supporting beneficial gut bacteria and regular bowel movements.
Vitamin E is added as part of an antioxidant blend to help support immune system function and cellular protection.
The formula is wheat-free and contains no fillers, artificial colors, flavors, or GMOs, making it suitable for cats with certain dietary sensitivities.
Balanced mineral levels, including 1.4% calcium, 1.2% phosphorus, and 0.098% magnesium, help support urinary tract health and maintain strong bones and teeth.

Moderate ash content

At 7%, the ash level may be a consideration for cats with kidney or urinary sensitivities.
3

Limited tuna content

Although labeled as a tuna formula, dried tuna accounts for only 4% of the recipe.

Unspecified vitamin levels

Most vitamin values are not disclosed, which limits transparency regarding micronutrient adequacy.

How the score is calculated?

The actual calculation of the score is based on sophisticated and advanced algorithm that takes into account multiple parameters.

To simplify the explanation, the calculation is based on three main criteria:

(1) Amount of protein (more is better)

(2) Amount of carbohydrates (less is better)

(3) Quality and source of ingredients.

Based on that 3 main criteria, 9 score calculation rules are used to compare the different foods.

One major assumption is that the closer an ingredient is to the top of the ingredient list, the greater its relative weight and contribution to the food.

In general, cat food is composed of protein, fats, carbohydrates, fibers, vitamins, and minerals.

Protein is the most important component in a cat's diet, and cats primarily get their protein from animal meat.

Fat is a primary source of energy and essential fatty acids.

Carbohydrates are controversial in a cat's diet, as cats are obligate carnivores and typically consume very few carbohydrates.

Fibers play an important role in digestion and food absorption, and vitamins and minerals are essential for different organism functions.

Dry matter values are used to compare the amount of nutrients in different cat foods. This means that moisture is excluded from the equation to provide a more accurate comparison.

Putting all of these and more into a formula results in a product score.

The maximum score a cat food can receive is 100. Points are added or removed based on the score calculation rules.
