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.

Tips

  • Protein is Medium (31% dry matter) on our label-based comparison range. This may be reasonable for many adult dogs, though active, growing, pregnant, or nursing dogs may need a more specific fit.

    Understanding Medium Protein (25% - 33% Dry Matter)

    Middle Comparison Bucket This bucket is species-aware: the cat medium range starts higher than the dog range. It helps compare labels, but it is not a complete nutrition verdict.

    Cats Need Closer Review Cats are obligate carnivores and generally need more protein than dogs. For cat foods in this range, the complete-and-balanced statement and life-stage claim are especially important.

  • Fat is High (17% dry matter) on our label-based comparison range. It can support calorie needs for active or growing dogs, but portion control and pancreatitis history deserve extra attention.

    Understanding High Fat (16% – 22% Dry Matter)

    Higher Calorie Density This range can support pets with higher energy needs, but it can also make overfeeding easier. Portion size, total calories, and body condition matter.

    Pancreatitis and Digestive History For dogs with pancreatitis history, fat level is often reviewed carefully. For cats, fat is only one part of the decision. Use this as a flag for vet-guided review, not as an automatic rejection.
