Summary

Ownat Just Grain Free – Sterilized Fish is a grain-free dry food formulated for sterilized adult cats to help maintain ideal weight while supporting healthy skin, coat, and digestion.
The first ingredient is dehydrated chicken (32%), making poultry the primary protein source, with additional fish proteins from fresh fish (12% before extrusion), hydrolyzed salmon, and dehydrated salmon to broaden amino acid diversity and supply omega-3s.
With 41% crude protein and 14% fat, the recipe emphasizes lean muscle maintenance alongside moderated calories suitable for neutered cats with normal activity levels.
Metabolizable energy is listed at 3,800 kcal/kg, so measured portions are important, especially for indoor or less active cats.
Declared omega-3 (0.6%) and omega-6 (2%) plus fish oil support skin barrier integrity and a shiny, silky coat.
Taurine (2,000 mg/kg) supports cardiac and retinal health, while L-carnitine (200 mg/kg) assists fat metabolism to aid weight control.
Prebiotic fibers (FOS and MOS), beet pulp, and brewer’s yeast help nourish beneficial gut bacteria and promote consistent stool quality.
Grain-free carbohydrate sources—peas, dehydrated potato, and cassava—provide energy while keeping fiber at 2.5% and moisture at 8% for kibble stability.
The mineral profile (calcium 1.6%, phosphorus 1.1%, ash 8.5%) supplies essential minerals, and functional additions like glucosamine (500 mg/kg), chondroitin (100 mg/kg), cranberries, marine algae, and selected herbs contribute joint nutrients and natural antioxidant compounds.
The recipe uses natural preservatives and excludes colorants, aligning with a complete and balanced formulation based on natural ingredients and fresh meats.

Pros
Expand All
1

High animal-protein profile

41% crude protein led by dehydrated chicken, with salmon and fresh fish, supports lean muscle in sterilized adults.
2

Skin and coat nutrition

Omega-3 at 0.6%, omega-6 at 2%, and fish oil help maintain skin barrier function and a glossy coat.
3

Weight-management support

L-carnitine at 200 mg/kg aids fat utilization while the high protein level helps preserve lean mass.
4

Digestive health aids

FOS, MOS, beet pulp, and brewer’s yeast provide prebiotic support for a balanced microbiome and regular stools.
5

Defined mineral levels

Stated calcium (1.6%) and phosphorus (1.1%) help support bone mineralization and overall metabolic function.
6

Antioxidant reinforcement

Vitamin E (425 IU/kg), vitamin C (100 mg/kg), and natural preservatives from plant sources contribute oxidative stress protection.
Cons
Expand All
1

Poultry is primary, not fish-only

Despite the name, the first ingredient is dehydrated chicken, which may not suit cats avoiding poultry.
2

Energy dense for weight control

At 3,800 kcal/kg, careful portioning is needed for indoor or low-activity sterilized cats to avoid weight gain.
3

Higher total mineral content

Ash at 8.5% indicates a relatively mineral-rich formula, which may warrant monitoring in cats needing tighter mineral control.
4

Modest fiber level

With 2.5% crude fiber, the diet may offer less satiety and hairball management than higher-fiber weight-control formulas.
5

Legume and tuber carbohydrates

Peas, potato, and cassava supply starch that can contribute to calorie intake and may not suit cats sensitive to legumes.
6

Added salt

Rock salt is included, which increases sodium—cats requiring sodium restriction may need a different formulation.

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.
