Science Plan - Adult Cat Food with Lamb & Rice
Summary
Hill’s Science Plan Adult Cat Food with Lamb & Rice is a complete dry diet for adult cats aged 1–6, designed to support digestive health, urinary balance, skin and coat condition, and steady energy needs.
The first ingredient, broken rice, is an easily digestible carbohydrate that provides quick, gentle energy for the gut.
Chicken and turkey meal are the primary animal protein sources to maintain lean muscle, while maize protein meal and pea protein contribute additional amino acids.
ActivBiome+ Multi-Benefit Technology combines prebiotic fibers and antioxidants—supported here by fructo-oligosaccharides, dried beet pulp, and oat bran—to nourish beneficial gut bacteria and promote regular stools.
At 32.5% crude protein and 20.2% fat with an energy density of 4,086 kcal/kg, the formula fuels active adult cats and may require portion control for less active indoor cats.
Balanced minerals—including calcium 0.77%, phosphorus 0.73%, and magnesium 0.07%—help support kidney and bladder health by moderating urinary mineral load.
Taurine at 0.19% supports normal heart function and vision, which are crucial for adult cats.
Fish oil and soybean oil supply omega-3 (0.43%) and omega-6 (3.07%) fatty acids, while vitamin E (744 IU/kg) and beta-carotene provide antioxidant support for skin, coat, and immune defenses.
Lamb meal appears at 4%, adding variety in animal proteins, though the recipe relies primarily on poultry meals for protein and broken rice for energy.
The low crude fiber level (0.9%) favors digestibility but offers limited satiety or hairball control, so individual needs should guide feeding amounts.

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.
