Marpet
Chef Grain Free Adult - Tuna and Salmon
Summary
Marpet Chef Grain Free Adult Tuna and Salmon is a grain-free dry food for adult cats, formulated with high animal protein from multiple fish sources.
Fresh tuna is the first ingredient at 30%, supported by 16% salmon meal and 10% herring meal for 56% marine-based proteins.
The 33% crude protein level and 16% fat provide a high-energy formula suitable for active adult cats with strong protein needs.
Linseed (2.5%) and fish oils provide a natural source of omega-3s, while peas and potatoes replace grains as carbohydrate sources.
Functional additives such as yucca (0.0265%), cranberry concentrate (0.004%), and seaweed (0.24%) support digestion, urinary health, and antioxidant function.
Hydrolyzed chicken and pork liver proteins (2%) contribute to flavor palatability and amino acid diversity without increasing whole organ load.
The energy density of 3,900 kcal/kg supports cats with active lifestyles but may be excessive for sedentary or indoor-only cats if not portioned carefully.
Pros:
High fish content: Contains 56% total fish proteins (tuna, salmon, herring), supporting lean muscle and omega-3 intake.
Energy-rich formulation: With 16% fat and 3,900 kcal/kg, the recipe meets the needs of high-activity adult cats.
Grain-free and gluten-free: Uses peas, potatoes, and broad beans as digestible carb alternatives for cats with grain sensitivities.
Botanical inclusions: Seaweed (0.24%), cranberry (0.004%), and yucca offer trace minerals, urinary support, and odor control.
Balanced nutrient profile: Provides essential vitamins (A, D3, E) and minerals like zinc (68 mg/kg) and selenium (0.16 mg/kg) for immune function.
Digestive and immune aid: Includes mannan-oligosaccharides (0.16%) from yeast to promote gut health.
Cons:
High calorie density: At 3,900 kcal/kg, careful portioning is needed to avoid weight gain in less active cats.
Moderate ash level: With 7.9% crude ash, it may not be suitable for cats with renal concerns or those needing mineral-restricted diets.
Limited taurine level: At 1,000 mg/kg, taurine content is below average compared to many premium high-protein recipes.
No DHA/EPA disclosure: Despite using marine proteins, specific omega-3 breakdown (DHA/EPA) is not provided.
No joint support nutrients: Glucosamine or chondroitin is not listed, which may be a drawback for older or joint-sensitive cats.
Broad protein mix: Multiple animal sources (tuna, salmon, herring, chicken, pork, turkey) may limit suitability for cats on elimination diets.

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.
