Summary

NutriSource Cat & Kitten Ocean Select is a grain-free dry cat food designed to support cats at all life stages with a high-protein, nutrient-dense formula.
The first ingredient is trout, a high-quality animal protein source rich in omega-3 fatty acids that support skin, coat, and heart health.
This recipe includes a blend of other premium animal proteins such as whitefish and salmon meals to create a total crude protein content of 40%, helping to build and maintain strong muscles and support energy levels.
Chickpeas and peas provide carbohydrate energy while contributing plant-based protein and fiber for digestive support.
The food is fortified with taurine, DL-methionine, and choline chloride to promote optimal cardiovascular health, vision, and liver function.
A proprietary blend of prebiotics, probiotics, and postbiotics (Good 4 Life® system and NGVEN) is included to nourish gut bacteria and enhance the digestion and absorption of nutrients.
Added goat’s milk from New Zealand and digestive enzymes further improve digestibility, aiding in the breakdown of proteins, fats, and carbohydrates.
Natural fish flavor and salmon oil ensure palatability, while flaxseeds and sunflower oil contribute to a healthy balance of omega-6 and omega-3 fatty acids.
The inclusion of glucosamine and chondroitin from natural animal sources helps support joint health, making this formula especially beneficial for both growing kittens and active adult cats.
High levels of Vitamin A, D, E, and B-complex vitamins round out the formula to support immune function, energy metabolism, and overall vitality.

Balanced omega-3 and omega-6 fatty acids from trout, flaxseed, and sunflower oil support skin, coat, and anti-inflammatory functions.
Cons
Expand All
1

Higher Ash Content

An ash level of 9.28% may be elevated for cats with specific urinary health concerns.
2

Complex Ingredient List

The inclusion of multiple legumes, yeast extracts, and fermentation products may not be suitable for cats with ingredient sensitivities.
3

High Caloric Density

With 500 kcal per cup, portion control is crucial to prevent overfeeding, particularly for indoor or less active cats.
4

Magnesium Level

Though within a reasonable range, the magnesium content of 0.16% could be higher than desired for cats prone to urinary crystals.

    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.
