Summary
Royal Canin Light Weight Care is a dry cat food formulated to help adult cats maintain a healthy body condition.
The primary protein source is dehydrated poultry protein, which contributes to a crude protein content of 36%, which supports muscle maintenance.
A blend of vegetable fibers, including psyllium husks and seeds, promotes satiety by increasing food volume in the stomach, helping to reduce spontaneous eating.
The formula contains only 10% crude fat, limiting calorie intake while preserving lean muscle mass.
L-carnitine (200 mg/kg) is included to support fat metabolism and manage weight.
Balanced minerals help maintain a healthy urinary system in adult cats.
With a fiber content of 10.4%, this diet supports digestion and helps control appetite in overweight or less active cats.
Pros:
High protein content: Contains 36% crude protein from dehydrated poultry protein, supporting muscle maintenance.
Low-fat formula: With 10% fat, it helps prevent excessive weight gain while maintaining energy balance.
Appetite control: Includes vegetable fibers and psyllium husks to promote fullness and reduce overeating.
L-carnitine enrichment: Supports fat metabolism, helping overweight cats manage their weight effectively.
Urinary health support: Balanced mineral content helps maintain a healthy urinary system.
Cons:
High fiber content: At 10.4%, it may not suit cats with certain digestive sensitivities.
Multiple plant-based ingredients: Contains maize, wheat, and vegetable protein isolate, which may not be ideal for obligate carnivores.
Potential allergens: Maize, wheat, and soya oil could trigger food sensitivities in some cats.
Unspecified animal fats: The source of animal fats is not clearly defined, which may concern pet owners looking for transparency in ingredients.

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.
