Summary
In Leonardo Adult GF Maxi, fresh poultry meat is the first ingredient, providing highly digestible, complete animal protein and essential amino acids to support lean muscle maintenance in adult cats.
With 80% of total protein derived from animal sources, including poultry, egg, and marine proteins, this formula ensures sustained energy and optimal tissue repair.
The use of amaranth instead of traditional grains supplies a gluten-free pseudo-cereal rich in fiber, minerals and antioxidants to promote gentle digestion and balanced blood sugar levels.
Pea flour, potato starch and chicory inulin offer a blend of digestible carbohydrates and prebiotic fibers that nurture a healthy gut microbiome and improve stool quality.
Functional fibers from guar gum and chia seeds facilitate the gentle transit of hairballs, helping cats pass ingested hair more efficiently.
Marine zooplankton (krill) and fish meal deliver omega-3 fatty acids and natural antioxidants to support skin, coat and joint health.
Extra-large kibble size slows chewing to stimulate saliva production and, combined with the Stay-Clean™ system, helps reduce plaque buildup for better dental health.
Specialized pH-Control components work to maintain optimal urinary pH, lowering the risk of crystal formation and promoting bladder comfort.
Enrichment with taurine, L-carnitine and a balanced mineral profile supports cardiovascular function, fat metabolism and bone strength for large-breed adult cats.
By replacing common cereal grains with amaranth, it is better tolerated by cats prone to grain sensitivities while remaining nutritionally complete for both indoor and outdoor lifestyles.

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.
