Nutritional information as published by the cat food manufacturer.*
The manufacturer's published guaranteed analysis values normalized for moisture content.
*Note that some nutritional percentages reported are only estimated values, and are indicated as such as (est). Each cat food manufacturer is required by law to publish a Guaranteed Analysis, which defines each product's maximum values of fiber, moisture and ash in addition to the minimum values of protein and fat contained within. Exact nutritional percentages are not available and hence all calculated values (including carbohydrate percentages and calorie amounts) are determined using these minimum and maximum published values and therefore may differ from actual values.
Although a high score may be indicative of a higher-quality product it is not a guarantee. Similarly, a low score may or may not indicate an inferior product. The best food for your cat is the one that meets their individual needs.
