Just Grain Free - Sterilized Fish
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.

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.
