Summary
Delcon Adult with Fish is a dry food for adult cats living indoors or outdoors, formulated around animal protein with chicken as the lead source.
The first ingredient is dehydrated chicken (29%), delivering highly digestible, complete amino acids that support lean muscle and daily metabolism.
Chicken fat provides a concentrated, palatable energy source, while dehydrated salmon (4%) adds marine nutrients and flavor variety.
At 31% crude protein and 18% fat, the recipe is energy-dense and well-suited to active cats, though portion control is advisable for more sedentary pets.
Sweet potato, potato flakes, peas, and split peas supply digestible carbohydrates and plant protein, contributing energy but shifting part of the protein fraction toward plant sources.
Dried beet pulp, cellulose, and 1% chicory (a source of FOS and inulin) provide fermentable and insoluble fibers that support stool quality and a healthy gut microbiome.
Brewer’s yeast (1%) and yeast extract (0.5% with MOS and beta-glucans) add prebiotic compounds that help nourish beneficial bacteria and support intestinal and immune function.
Skin and coat health is supported by salmon oil (0.5%) and linseed for omega fatty acids, plus zinc and vitamin E (500 mg/kg) with natural tocopherols for antioxidant protection.
Taurine (2500 mg) and DL-methionine (5000 mg) supply essential sulfur amino acids; DL-methionine is also commonly used to help maintain urinary acidity.
Minerals are declared with calcium at 1.1% and phosphorus at 0.9%, and joint nutrients glucosamine and chondroitin (100 mg/kg each) provide added cartilage support for active adults.
Pros:
- Primary animal protein first: Dehydrated chicken (29%) leads the recipe, providing complete, highly digestible amino acids for muscle maintenance.
- Skin and coat support: Salmon oil (0.5%), linseed, zinc, and vitamin E (500 mg/kg) supply omega fats and antioxidants that help promote a healthy skin barrier and shiny coat.
- Digestive health and microbiome: Beet pulp, cellulose, and 1% chicory (FOS/inulin), plus MOS and beta-glucans from yeast, support stool quality and beneficial gut bacteria.
- Amino acid and urinary support: Taurine (2500 mg) supports heart and vision, while DL-methionine (5000 mg) is often included to help maintain appropriately acidic urine.
- Joint nourishment: Glucosamine and chondroitin (100 mg/kg each) contribute structural nutrients for cartilage and joint resilience.
- Balanced macro-mineral declaration: Calcium at 1.1% and phosphorus at 0.9% support skeletal health and mineral balance.
Cons:
- High energy density: With 18% crude fat, the food delivers concentrated calories that may require careful portioning for less active indoor cats.
- Plant-heavy carbohydrate mix: Sweet potato, potato flakes, peas, and split peas increase carbohydrate and plant-protein contribution, which may not suit owners seeking a more meat-forward or lower-carb diet.
- Mixed protein sources: Chicken, salmon, and liver hydrolysate reduce suitability for cats needing single-protein, limited-ingredient diets for sensitivities.
- Fish is a minor component: Dehydrated salmon is present at 4%, so the primary protein remains chicken despite the “with Fish” positioning.
- Moderate ash: At 6%, overall mineral load is not low, which may be a consideration for cats that require stricter mineral management under veterinary guidance.

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.
