Adult Cats Chicken & Rice
Summary
Rex Natural Range Adult Cats Chicken & Rice is a complete dry cat food formulated for active adult cats, focusing on energy, urinary support, and coat health.
The primary protein sources include “flour of bird” and hydrolyzed chicken liver, which contribute to a crude protein content of 30%, which is necessary to maintain lean muscle mass.
The formula includes chicken oil and fish flour, delivering 13% crude fat and a balance of omega-3 and omega-6 fatty acids for coat shine and reduced skin inflammation.
Rice, corn, wheat, and green peas provide carbohydrates, energy, and fiber, while chicory and yeast help stimulate digestive health.
Sodium bisulfate (5,000 mg/kg) is included to regulate urinary pH and reduce the risk of crystal formation, supporting urinary tract health.
The food contains 930 mg/kg of taurine for cardiovascular and visual function, with DL-methionine (500 mg/kg) for urinary system support.
Ash content is 7%, calcium 1.4%, and phosphorus 1.1%, reflecting a moderate mineral load to support skeletal and metabolic health.
Pros:
High protein and fat content: 30% protein and 13% fat support active cats’ energy and muscle needs.
Urinary health formulation: Sodium bisulfate helps maintain ideal urinary pH and prevent crystal formation.
Skin and coat benefits: Omega-3 and omega-6 fats from fish and chicken oils promote dermal and coat health.
Digestive support: Inclusion of yeast and fiber helps improve intestinal transit and manage hairballs.
Balanced micronutrients: Contains taurine, methionine, and essential vitamins and minerals for systemic health.
Cons:
Low transparency in meat sources: “Flour of bird” is vague and not species-specific, which may affect quality perception.
Grain-heavy formula: This formula includes corn, wheat, and rice, which could be problematic for cats with grain intolerances.
No fresh meat inclusion: Relies solely on rendered meat meals and hydrolysates rather than fresh or raw proteins.
Moderate ash level: At 7%, ash may be high for cats with renal sensitivity or those prone to urinary conditions.
No joint support ingredients: It lacks glucosamine or chondroitin, which are beneficial for long-term mobility.

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.
