Why we do not rate pet food A-B-C-D-E
Posted: Tue Apr 28, 2026 9:16 am
This section explains why the Petfood Advisor approach does not rely on simplified rating systems such as A, B, C, D, or E.
At first glance, these types of scores seem practical. They provide a quick answer and create the impression of clarity. However, pet nutrition is far more complex than a single letter can represent. Reducing a product to one final grade removes context and can lead to misunderstandings.
One of the main limitations of these systems is their inability to reflect individual needs. Every animal is different, and a food that may be suitable in one situation may not be appropriate in another. A universal score ignores factors such as age, activity level, health status, and tolerance.
Another issue lies in how these scores are calculated. They are often based on simplified criteria, subjective weighting, or incomplete data. Important aspects of a formulation may be overlooked, while others are overemphasized. This can result in misleading conclusions that do not accurately represent the overall product.
These ratings can also influence behavior in unintended ways. A high score may create excessive confidence, while a low score may trigger unnecessary concern or abrupt dietary changes. In both cases, the decision is driven by the score rather than by a full understanding of the product.
For these reasons, the Petfood Advisor approach avoids assigning final grades. Instead, it focuses on providing structured information and analytical tools that help users interpret data, compare products, and develop their own informed perspective.
The goal is not to simplify decisions to a single letter, but to encourage a more thoughtful and contextual understanding of pet food.
