Summary
Delcon Sterilized Grain-Free ALS is a dry formula for sterilized cats, suitable for both indoor and outdoor lifestyles, with a nutrient profile geared toward maintaining a healthy body condition.
Its first ingredient is dehydrated chicken (35%), providing concentrated animal protein to help preserve lean muscle in neutered cats.
The overall profile—34% crude protein, 11% fat, 5% fiber, and 3661 kcal/kg—offers moderate energy with higher fiber to support satiety between meals.
Grain-free carbohydrates from peas, sweet potato, and potato flakes deliver digestible energy and fiber, with peas also contributing plant-derived protein.
A multi-fiber and prebiotic blend (beet pulp, cellulose, dried chicory as natural FOS/inulin, and yeast extract supplying MOS and beta-glucans) supports balanced gut microbiota, stool quality, and regularity.
Salmon oil (0.5%) and linseed add omega fatty acids that help nourish skin and coat while contributing anti-inflammatory support.
Calcium at 1.2% and phosphorus at 0.9% help manage mineral intake for bone maintenance and to moderate urinary and kidney workload.
Taurine (2500 mg) supports heart function and vision, and L-carnitine (50 mg) assists fat metabolism—valuable for sterilized cats prone to weight gain.
Glucosamine and chondroitin (100 mg/kg each) provide supplemental joint support for active or heavier cats.
Natural antioxidants, including vitamin E (500 mg/kg) and tocopherol extracts, help protect fats from oxidation and support overall antioxidant status.

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.
