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:

• Animal-first protein focus: Dehydrated chicken as the first ingredient (35%) supplies concentrated, highly usable protein for lean muscle maintenance.

• 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.

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

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

• 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.

• 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:

• Higher starch contributors: Peas, sweet potato, and potato flakes likely increase carbohydrate load, which may not suit cats requiring very low-carb diets.

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

• Modest marine omega-3 inclusion: Salmon oil at 0.5% suggests a limited contribution of EPA and DHA.

• 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.

• Moderate ash content: Ash at 6.5% indicates minerals are not particularly low; cats with specific urinary or kidney needs may require individualized guidance.

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