Summary

Hill’s Science Plan Mature Adult 7+ Chicken is a dry food formulated to support graceful aging and maintain energy and activity in cats 7 years and older.
The first ingredient is chicken and turkey meal, providing concentrated poultry protein to help preserve lean muscle in senior cats.
At 30.6% crude protein and 18.9% fat with 3936 kcal/kg, it delivers an energy-dense profile that fuels active seniors, though portion control is important for less active cats.
A balanced mineral profile—phosphorus 0.65%, calcium 0.81%, magnesium 0.077%, and sodium 0.33%—supports urinary tract health and helps manage mineral load on aging kidneys.
Taurine at 0.2% supports normal heart function and vision, both essential for older felines.
Omega-6 at 3.53% and omega-3 at 0.74%, supported by fish oil, flaxseed, poultry fat, and soybean oil, promote healthy skin, a glossy coat, and an anti-inflammatory balance.
Vitamin E at 896 IU/kg, vitamin C, and beta-carotene provide antioxidant defense that helps counteract age-related oxidative stress.
L-carnitine at 569.4 ppm supports fat metabolism, helping maintain lean mass and healthy body condition in seniors.
Easy-to-digest grains and natural fibers from oat bran, flaxseed, and added fructo-oligosaccharides support gentle digestion and regular stools.

Pros
Expand All
1

Primary animal protein from poultry meal

Chicken and turkey meal offer concentrated, highly digestible protein to support muscle maintenance in older cats.
2

Controlled minerals for urinary support

Phosphorus (0.65%), magnesium (0.077%), calcium (0.81%), and sodium (0.33%) help support healthy urinary function and reduce mineral burden on kidneys.
3

Robust antioxidant support

Vitamin E (896 IU/kg), vitamin C (102 ppm), and beta-carotene (2.78 ppm) help neutralize free radicals associated with aging.
4

Skin and coat nutrition

Omega-6 (3.53%) and omega-3 (0.74%) from fish oil and flaxseed support skin barrier integrity, coat sheen, and inflammatory balance.
5

Metabolic support with L-carnitine

569.4 ppm L-carnitine assists fat utilization, aiding healthy weight and energy metabolism in seniors.
6

Digestive comfort

Easy-to-digest ingredients plus fructo-oligosaccharides and natural fibers help maintain regular stools and gut health.
Cons
Expand All
1

High energy density

With 18.9% fat and 3936 kcal/kg, the diet may be too calorie-dense for overweight or sedentary seniors without careful portion control.
2

Moderate carbohydrate load

Carbohydrate (NFE) at 38.1% from multiple grains may not suit cats whose owners prefer lower-carb or grain-free feeding strategies.
3

Plant protein contribution

The presence of maize protein meal suggests some protein is plant-derived, which may be less optimal for obligate carnivores needing a higher share of animal protein.
4

Low crude fiber

At 1.1% crude fiber, the formula may offer less support for hairball control or satiety compared with higher-fiber senior options.
5

Multiple animal proteins

Inclusion of both chicken and turkey can complicate elimination diets for cats with specific protein sensitivities.
6

EPA/DHA not specified

While total omega-3 is listed (0.74%), the exact EPA/DHA levels are not provided, limiting clarity on targeted anti-inflammatory support.

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.
