Nutri Pet Score

NutriPetScore: Definition and Purpose

NutriPetScore is a scoring system developed to assess the nutritional quality of complete wet cat foods. This system aims to provide an objective guide to pet owners in choosing high-quality food for their cats, taking into account various nutritional parameters and ingredient transparency.

NutriPetScore Objectives

1. Educate Consumers : Help cat owners make informed decisions about the nutritional quality of wet foods available on the market.
2. Promote Transparency : Encourage brands to provide clear and detailed information about the composition of their products.
3. Promote Proper Nutrition : Ensure that cats receive a balanced and nutritious diet appropriate to their nutritional needs.

NutriPetScore Criteria and Calculation Process

The NutriPetScore is calculated following a series of detailed steps, taking into account the nutritional composition and ingredients of the food. The calculation process is described below:

1. Key Nutrients :
• Protein : Should be within the ideal range of 26% to 66% on a dry basis. Proteins are crucial for tissue growth and repair.
• Fats : Should be within the range of 9% to 28% on a dry basis. They provide energy and essential fatty acids.
• Ash : Ideally between 9% and 14.9% on a dry basis, indicating the amount of minerals.
• Carbohydrates : Should be between 0% and 12.9% on a dry basis. Cats require low levels of carbohydrates.
2. Conversion to Dry Base (DMB) :
• Nutrient values ​​on a moisture basis are converted to a dry basis for accurate comparison using the formula: Value in DMB=(Value on moisture basis100−Moisture)×100\text{Value in DMB} = \left( \frac{\text{Value on moisture basis}} {100 - \text{Moisture}} \right) \times 100Value in DMB=(100−MoistureValue on moisture basis​)×100
3. Score Calculation :
• Each nutrient receives a score of 10 if it is within the ideal range.
• If a nutrient is outside the ideal range, the score is adjusted proportionally: Fat Score=(Upper limit of ideal rangeCalculated value)×5+5\text{Fat Score} = \left( \frac{\text{Upper limit of ideal range}} {\text{Calculated value}} \right) \times 5 + 5Fat Score=(Calculated valueUpper limit of ideal range​)×5+5
4. Penalties for Ingredients :
• Fruits and Vegetables : Penalty proportional to the percentage of the product. If the percentage is greater than 10%, a penalty of 20% is applied.
• Unwanted Ingredients : 10% penalty for each unwanted ingredient, such as starches, sugars, and gums.
• Fish and Fish By-Products : Penalty of 20% to 40% depending on the percentage, with exceptions such as salmon oil and green-lipped mussels.
5. Transparency on the Label :
• Lack of transparency in the description of ingredients is penalized (e.g. "meats and animal by-products" without specifying).
6. Final Score Calculation :
• The total score is calculated by averaging the nutrient scores and applying any penalties:

Final Score=Protein+Fat+Ash+Carbohydrates4\text{Final Score} = \frac{\text{Protein} + \text{Fat} + \text{Ash} + \text{Carbohydrates}} {4}Final Score=4Protein+Fat+Ash+Carbohydrates​

• Penalties are applied by multiplying the total score by (1 - total penalty).

Calculation Example

Let's suppose a product with the following composition:

• Ingredients : 80% chicken meat, 15% chicken broth, 5% minerals.
• Analytical Components :
• Proteins: 14%
• Fats: 6%
• Ashes: 2%
• Fibers: 0.5%
• Humidity: 78%

Step 1: Calculate Carbohydrates Carbohydrates = 100 − (14 + 6 + 2 + 0.5 + 78) = 0.5%\text{Carbohydrates} = 100 - (14 + 6 + 2 + 0.5 + 78) = 0.5\%Carbohydrates = 100 − (14 + 6 + 2 + 0.5 + 78) = 0.5%

Step 2: Convert to Dry Basis (DMB)

Proteins (DMB)=(1422)×100≈63.64%\text{Proteins (DMB)} = \left( \frac{14}{22} \right) \times 100 \approx 63.64\% Proteins (DMB)=( 2214​)×100≈63.64% Fat (DMB)=(622)×100≈27.27%\text{Fat (DMB)} = \left( \frac{6}{22} \right) \times 100 \approx 27.27 \% Fat (DMB)=(226​)×100≈27.27% Ash (DMB)=(222)×100≈9.09%\text{Ashes (DMB)} = \left( \frac{2}{22} \right) \times 100 \approx 9.09\% Ashes (DMB)=(222 ​)×100≈9.09% Carbohydrates (DMB)=(0.522)×100≈2.27%\text{Carbohydrates (DMB)} = \left( \frac{0.5}{22} \right) \times 100 \approx 2.27\ % Carbohydrates (DMB)=(220.5​)×100≈2.27%

Step 3: Nutrient Score

• Proteins: 10
• Fats: 10
• Ashes: 10
• Carbohydrates: 10

Step 4: Penalties

• There are no penalizing ingredients.

Step 5: Calculate Final Score

Final Score=10+10+10+104=10\text{Final Score} = \frac{10 + 10 + 10 + 10}{4} = 10 Final Score=410+10+10+10​=10

Additional Considerations

• Food Rotation : It is recommended to switch between brands to ensure a varied diet.
• Origin of Raw Materials : The origin of the raw materials is not taken into account.
• Individuality of Each Cat : The specific needs of the cat must be considered.

The NutriPetScore is a useful tool for assessing the nutritional quality of wet cat food, but it should be complemented by the assessment of other factors, such as the cat's health and veterinary recommendations.

PetScore: Definition and Rules

PetScore is a scoring system designed to assess the nutritional quality of wet cat foods, based on specific parameters defined by nutritional standards for cats. This system takes into account the nutrient composition of the product, the transparency of ingredients and the presence of unwanted ingredients.

PetScore Calculation Example

Step 1: Composition and Analysis of Components

• Protein: 14.0%
• Fats: 3.0%
• Ashes: 2.0%
• Fibers: 0.9%
• Humidity: 75.0%
• Carbohydrates: 100−(14.0+3.0+2.0+0.9+75.0)=5.1%100 - (14.0 + 3.0 + 2.0 + 0.9 + 75.0) = 5.1\%100−(14.0+3.0+2.0+0.9+75.0)=5.1%

Step 2: Convert to Dry Basis (DMB)

• Proteins: (14.025)×100≈56%\left( \frac{14.0}{25} \right) \times 100 \approx 56\%(2514.0​)×100≈56%
• Fats: (3.025)×100≈12%\left( \frac{3.0}{25} \right) \times 100 \approx 12\%(253.0​)×100≈12%
• Ashes: (2.025)×100≈8%\left( \frac{2.0}{25} \right) \times 100 \approx 8\%(252.0​)×100≈8%
• Fibers: (0.925)×100≈3.6%\left( \frac{0.9}{25} \right) \times 100 \approx 3.6\%(250.9​)×100≈3.6%
• Carbohydrates: (5.125)×100≈20.4%\left( \frac{5.1}{25} \right) \times 100 \approx 20.4\%(255.1​)×100≈20.4%

Step 3: Nutrient Score

• Proteins: 10 (within the ideal range)
• Fats: 10 (within the ideal range)
• Ashes: (89)×5+5≈8.44\left( \frac{8}{9} \right) \times 5 + 5 \approx 8.44(98​)×5+5≈8.44
• Carbohydrates: (12.920.4)×5+5≈8.16\left( \frac{12.9}{20.4} \right) \times 5 + 5 \approx 8.16(20.412.9​)×5+5≈8.16

Step 4: Apply Penalties

• No additional penalties (no penalty ingredients)

Bottom line

• Total score without penalties: (10+10+8.44+8.16)4=9.15\frac{(10 + 10 + 8.44 + 8.16)}{4} = 9.154(10+10+8.44+8.16)​=9.15

Conclusion

The PetScore is based on a thorough analysis of key nutrients, label transparency and the absence of unwanted ingredients. This scoring system allows the nutritional quality of wet cat foods to be objectively assessed, helping pet owners make informed decisions about feeding their cats.

It should be added that due to the lack of information on the labels of the products we are not able to analyse the calcium, phosphorus, the ca:p ratio and some of the ingredients that they may contain and which we are not obliged to provide in the information. On the other hand, it should be stressed that the nutripetscore only works for complete wet food for cats, and that it should not be taken as the only way to evaluate a food.

Returning to the description of nutripetscore, we must also warn that it is important to maintain a rotation of foods from different brands, that we do not take into account the origin of the raw materials used, that each cat is different and that in any case the wet food with a lower score will always be better than any feed on the market.
