Chef Grain Free Sterilized - Turkey and Chicken
Summary
Marpet Chef Grain Free Sterilized is a dry cat food for neutered adult cats with moderate energy needs and grain sensitivity.
Fresh turkey is the first ingredient at 30%, followed by 16% processed chicken protein and 10% herring meal for a diversified and high-quality animal protein base.
The formula contains 33% crude protein and 14% fat, offering a balanced nutrient profile tailored for weight control post-sterilization.
Potatoes, peas, and broad beans replace cereals as carbohydrate sources in this grain-free and gluten-free recipe.
Linseed (2%) and herring meal provide beneficial omega-3 fatty acids, while added beet pulp supports digestive regularity.
Cranberry concentrate (0.004%), seaweed (0.24%), and Yucca schidigera (0.033%) offer functional botanical benefits for urinary tract health, anti-inflammatory support, and odor control.
With 2,000 mg/kg taurine and an energy density of 3,600 kcal/kg, the food meets the essential health requirements of sterilized indoor cats.
Pros:
Fresh turkey as first ingredient: This product contains 30% fresh turkey and 56% animal protein sources, including herring and chicken, for high-quality nutrition.
Sterilized-specific formulation: Balanced 33% protein and 14% fat composition helps maintain healthy weight and lean muscle in neutered cats.
Digestive support: This product includes 3% fiber from beet pulp, peas, and linseed to support digestive function and stool quality.
Botanical inclusions: Uses cranberry, yucca, and seaweed to support urinary tract health, reduce stool odor, and provide micronutrients.
Free from common allergens: Grain-free and gluten-free with no added dyes or preservatives, reducing the risk of food sensitivities.
Functional yeast components: Contains MOS from yeast (0.16%) to aid gut health and immune function.
Cons:
Moderate ash level: At 7.5% crude ash, the mineral content may be on the higher side for cats with kidney concerns.
Low DHA/EPA data: No explicit omega-3 breakdown or DHA/EPA levels listed despite the inclusion of herring and linseed.
No probiotics guaranteed: Although yeast is included, there is no specified probiotic count or strain provided.
Limited organ meats: Hydrolyzed liver is included but not quantified in the breakdown, limiting evaluation of vitamin A sources.
No joint support nutrients: The Formula lacks glucosamine or chondroitin, which may benefit aging sterilized cats.
Cranberry inclusion minimal: At only 0.004%, the actual urinary support from cranberry may be limited despite the claim.

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.
