Summary

Purizon Original Grain-Free Fish (New Recipe) is a grain-free, fish-forward dry cat food designed for indoor and outdoor cats that emphasizes high animal protein to match carnivorous physiology.
The first ingredient, herring protein (30%), provides concentrated, highly digestible amino acids, complemented by 26% fresh herring and 5% hydrolyzed fish protein to further support muscle maintenance.
With 44% crude protein, the recipe supports lean body mass and daily tissue repair in active and sedentary cats alike.
At 20% fat and 3970 kcal/kg, it is calorie-dense to fuel active or outdoor cats with higher energy needs.
Fish oil (4%) plus an omega-3 level of 1.4% and omega-6 at 3.1% help maintain skin integrity, a glossy coat, and a healthy inflammatory balance.
Taurine at 2200 mg supports normal heart function and vision, which are essential for feline health.
L-methionine (4000 mg) contributes to urinary tract care by helping maintain a favorable urinary environment, while calcium (1%) and phosphorus (0.9%) provide balanced macro-minerals for bones and teeth.
Inulin and mannan-oligosaccharides act as prebiotics, while dried apple pomace and 2% linseeds add functional fiber to aid digestion and stool quality; Mojave yucca can help reduce stool odor.
Chelated trace minerals (zinc, manganese, iron, copper) and selenium yeast may improve mineral availability, and antioxidants including vitamin E (650 IU) and vitamin C (300 mg) support cellular protection.
Carbohydrate sources such as peas, pea protein, pea meal, and potato supply energy and give kibble structure, which may not suit cats that need legume-free diets.

Pros
Expand All
1

Marine-first protein profile

Herring protein (30%) with fresh herring (26%) provides concentrated, digestible amino acids that support lean muscle.
2

Skin and coat support

Fish oil (4%) with omega-3 at 1.4% and omega-6 at 3.1% helps maintain skin barrier function and a shiny coat.
3

Urinary and mineral balance

L-methionine (4000 mg) aids urinary tract care, and balanced calcium (1%) and phosphorus (0.9%) support bones and teeth.
4

Digestive health aids

Inulin and MOS act as prebiotics, while apple pomace and linseeds provide fiber for stool quality; yucca helps reduce stool odor.
5

Cardiac and visual protection

Taurine at 2200 mg supports normal heart muscle function and retinal health.
6

Bioavailable micronutrients and antioxidants

Chelated trace minerals and selenium yeast enhance mineral uptake, while vitamin E (650 IU) and vitamin C (300 mg) provide antioxidant support.
Cons
Expand All
1

High energy density

With 20% fat and 3970 kcal/kg, the formula may be too calorie-dense for less active or weight-prone cats.
2

Legume and potato inclusion

Peas, pea protein, pea meal, and potato add plant proteins and carbohydrates, which may not suit owners seeking legume-free or lower-carb diets.
3

Moderate-to-high ash

At 8.5% crude ash, the mineral load may warrant caution for cats with known urinary or kidney sensitivities.
4

Multiple fish protein sources

The use of several fish ingredients can limit suitability for cats needing single-protein, limited-ingredient diets.
5

Magnesium not disclosed

Lack of magnesium data makes it harder to fully assess the urinary mineral profile.
6

No live probiotics listed

The recipe includes prebiotics (inulin, MOS) but does not specify any added live probiotic cultures.

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.
