Leger Weight Control
Summary
Josera Léger is a complete dry cat food tailored for adult cats with low activity levels or a tendency to gain weight, such as after neutering.
It uses dried poultry protein as the primary ingredient, offering a digestible animal protein source while maintaining a moderate fat level of 10%.
The recipe is designed for calorie control, and it contains increased dietary fibre (5.8%) to enhance satiety and support digestion.
L-carnitine is included to support fat metabolism, which is beneficial for weight management.
It also features an adjusted mineral profile and reduced magnesium content (0.09%) to promote a healthy urinary pH of 6.0–6.5.
The formulation contains psyllium husks and specific fibres to help reduce hairball formation by supporting hair transit through the digestive tract.
This food is especially suited to indoor or sterilized cats requiring lower caloric intake without compromising essential nutrition.
Pros:
Weight management: 10% fat and the inclusion of L-carnitine help maintain a healthy weight and metabolize fat efficiently.
Satiety support: Elevated crude fibre content (5.8%) and specific fibres enhance feelings of fullness, reducing overeating.
Anti-hairball formulation: Contains psyllium husks and dietary fibres that aid in moving ingested hair through the gut, reducing hairball risk.
High protein content: At 35%, the protein level supports lean muscle mass even during calorie-restricted feeding.
Urinary tract health: Balanced minerals and a magnesium content of just 0.09% help maintain a urinary pH between 6.0–6.5 to reduce the risk of urinary stone formation.
Cons:
First ingredient is not fresh meat: The primary protein source is dried poultry protein rather than fresh meat, which may be less palatable to some cats.
Moderate phosphorus level: At 1.05% phosphorus, it may be less suitable for senior cats or those with early renal issues.
High grain content: This includes whole-grain corn and rice, which are less desirable for cats with grain sensitivities or allergies.
There are no omega-3 and -6 data listed. The product does not specify levels of omega fatty acids, which are important for supporting skin, coat, and inflammation.
No probiotic support: While fibre is provided, live probiotics to enhance gut microbiome balance are not included.

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.
