Marpet
Chef Grain Free Adult - Turkey and Duck
Summary
Marpet Chef Grain Free Turkey and Duck is a dry cat food formulated without grains for adult cats. It features high meat inclusion and functional botanicals.
Fresh turkey is the first ingredient at 30%, supported by 14% processed duck and 15% chicken protein, offering 59% animal-based ingredients.
The recipe provides 33% crude protein and 16% crude fat, giving it an energy-rich profile suitable for active adult cats or those with higher metabolic needs.
Including peas, potatoes, and broad beans replaces grain-based carbs and contributes to overall digestibility.
Natural additives include 0.004% cranberry concentrate for urinary tract support, 0.24% seaweed for mineral balance, and 0.0265% yucca to assist with stool odor.
Linseed (2%) offers a plant-based source of omega-3s, aiding skin and coat health, while hydrolyzed liver proteins (1%) enhance palatability and amino acid variety.
With a metabolic energy value of 3,900 kcal/kg, this food supports active lifestyles but requires measured feeding for less active cats.
Pros:
Rich in poultry proteins: A high animal protein blend (turkey, duck, chicken) supports lean muscle development and taste preference.
Energy-dense formula: With 16% fat and 3,900 kcal/kg, this food suits cats with higher caloric requirements or outdoor lifestyles.
Botanical enhancements: Includes cranberry, yucca, and seaweed for urinary support, gut health, and trace nutrients.
Grain-free and gluten-free: Uses vegetable sources like peas and potatoes to avoid common allergens.
Balanced nutrition: Provides essential vitamins (A, D3, E) and minerals like zinc (68 mg/kg) and selenium (0.16 mg/kg) for immune and metabolic support.
Functional prebiotics: Mannan-oligosaccharides (0.16%) from yeast promote beneficial gut bacteria.
Cons:
No DHA/EPA data: Despite including animal fats and linseed, the omega-3 breakdown (DHA/EPA) is not explicitly disclosed.
Moderate ash content: At 7.9%, the ash level may be unsuitable for cats with renal sensitivity or special mineral restrictions.
Limited taurine inclusion: It contains 1,000 mg/kg of taurine, which is low for modern high-protein diets.
Broad protein spectrum: Including turkey, duck, and chicken may complicate feeding for cats needing limited ingredient diets.
There are no joint support nutrients, such as Glucosamine or chondroitin, making it less ideal for older cats with mobility concerns.
No probiotic claim: Although MOS is included, the product does not specify live probiotics or CFU levels.

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.
