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.

Pros
Expand All
1

Animal-first protein focus

Dehydrated chicken as the first ingredient (35%) supplies concentrated, highly usable protein for lean muscle maintenance.
2

Balanced for sterilized cats

34% protein, 11% fat, and 5% fiber with 3661 kcal/kg provide moderate energy and satiety support for body-weight control.
3

Digestive support

Beet pulp, cellulose, chicory (FOS/inulin), and yeast-derived MOS/beta-glucans promote a healthy gut environment and consistent stools.
4

Mineral management

Calcium at 1.2% and phosphorus at 0.9% help support bone health and reduce excess mineral load on the urinary tract.
5

Skin, coat, and antioxidant care

Salmon oil, linseed, and vitamin E (500 mg/kg) provide fatty acids and antioxidants that support skin, coat, and oxidative balance.
6

Targeted functional additives

Taurine (2500 mg) supports heart and eye health, and L-carnitine (50 mg) aids fat metabolism; glucosamine and chondroitin (100 mg/kg each) add joint support.
Cons
Expand All
1

Higher starch contributors

Peas, sweet potato, and potato flakes likely increase carbohydrate load, which may not suit cats requiring very low-carb diets.
2

Mixed protein sources

Peas add plant-derived protein, so not all protein is animal-based—a consideration for owners prioritizing exclusively animal protein.
3

Modest marine omega-3 inclusion

Salmon oil at 0.5% suggests a limited contribution of EPA and DHA.
4

Elevated fiber level

At 5% crude fiber, the formula may reduce caloric density and increase stool bulk, which may not fit very active or underweight cats.
5

Moderate ash content

Ash at 6.5% indicates minerals are not particularly low; cats with specific urinary or kidney needs may require individualized guidance.
6

Contains poultry

Chicken-based proteins and fats make it unsuitable for cats with known poultry sensitivities.

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.
