Summary

Hill’s Science Plan – Mature Adult 7+ Chicken is a dry cat food formulated to support the health and vitality of senior cats aged 7 years and older.
The first ingredient is chicken (13%), a high-quality animal protein that helps maintain lean muscle mass in aging cats.
Turkey meal (7%) further contributes to the total poultry content (20%), offering additional digestible protein and essential amino acids.
With a crude protein level of 30.8% and fat at 17.3%, the formula provides a balanced energy profile to support the reduced activity levels typical of older cats while helping to prevent muscle loss.
Essential taurine (0.2%) is included to support cardiac function, which is especially important in senior felines prone to heart issues.
Balanced mineral levels, including phosphorus (0.64%), calcium (0.72%), and magnesium (0.08%), help maintain kidney and urinary tract health, which are common areas of concern in aging cats.
Omega-3 (0.7%) and omega-6 (3.3%) fatty acids from flaxseed and fish oil promote healthy skin and a shiny coat, while also offering anti-inflammatory benefits.
Natural fibers from ingredients like wheat and brewers’ rice support digestive health and stool quality, making the food easier to process for older digestive systems.
Antioxidants such as vitamin E (800 mg/kg), vitamin C (90 mg/kg), and beta-carotene help neutralize free radicals, supporting immune function and cellular health.
With a metabolizable energy of 4145 kcal/kg, the food is energy-dense, allowing senior cats to meet their caloric needs with smaller portions, which can be beneficial for cats with reduced appetites.

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.
