Protein Clarity

Protein Clarity

This measures how clearly the protein sources are identified on the label. "High" means ingredients like "chicken" or "salmon" are listed by name, so you know exactly what your pet is eating. "Low" means vague terms like "meat meal" or "animal by-products" are used, making it harder to know what's really inside.

Why does clarity matter?

According to AAFCO (Association of American Feed Control Officials), pet food labels must follow specific naming standards. When a product uses a named protein like "chicken" it must contain at least 25% of that ingredient. Vague terms like "meat by-products" have no such minimum and can include lower-quality parts from any animal source — making it impossible to know what your pet is actually eating or to identify allergens.

High
Animal Protein

Animal Protein

This estimates how meat-forward the protein sources are from the ingredient label. Named animal proteins count strongly, plant protein concentrates count strongly against the score, and whole plant ingredients with some protein count more lightly. A "High" score means the recipe appears mainly animal-protein led. A "Low" score means the label shows a stronger reliance on plant protein signals.

This is an ingredient-label heuristic, not an exact lab measurement of protein grams.

Why does animal protein matter?

1. Contains irreplaceable essential nutrients Taurine and Arginine — which cats need to stay healthy — are only found in meat. Plants contain none at all.

2. Plant proteins are poorly utilized by the body Even though plant proteins (like corn gluten meal) may show 92.9–96% apparent digestibility, that does not mean high bioavailability. They lack adequate Lysine (only 1.7% vs. the ideal 6–7%) and contain phytic acid that blocks mineral absorption.
