Pet Food Score - Petfood Advisor

Hello everyone,

I have seen that there are many different ABCDE scoring systems for pet food, and it looks like each one uses its own method and criteria. This makes it difficult to understand how the final grade is calculated and to compare products fairly.

Could you please explain which criteria are usually taken into account for these ABCDE scores (for example: ingredient quality, meat content, additives, processing level, nutrient balance, etc.)? And is there any way to know in detail how each system weights these factors, since there are many different approaches?

Thank you in advance for your explanations and for helping to clarify how these ratings actually work.
