Summary

LEONARDO Adult Duck is a poultry-focused dry cat food formulated for adult cats, featuring fresh poultry meat as the first ingredient, which serves as a highly digestible and palatable source of animal protein essential for muscle maintenance.
With 85% of the total protein derived from animal sources, this recipe provides optimal amino acid availability, essential for energy metabolism and maintaining lean body mass.
The inclusion of duck protein adds variety to the protein profile while supporting cats that prefer novel poultry meats.
Krill, a marine zooplankton, is a natural source of Omega-3 fatty acids, which help maintain healthy skin and a glossy coat, while supporting brain and heart health.
Chia seeds contribute further Omega-3s and provide fiber, aiding in digestion and helping with hairball control, supported by added guar gum and inulin for GI health.
The formula includes STAY-CLEAN™ to support dental hygiene by reducing plaque formation, contributing to better oral health.
Lecithin and tocopherol extracts (natural vitamin E) enhance the bioavailability of fatty acids and support cellular protection.
Added vitamins such as A, D3, and E aid vision, bone health, and immune defense, while essential minerals like zinc, iron, and copper contribute to immune and skin function.
pH control ensures urinary tract health by optimizing the urine environment, essential for preventing issues like struvite crystal formation.
This product is suitable for both indoor and outdoor adult cats needing a poultry-based diet with enhanced skin, coat, and digestive benefits.

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.
