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.

Low
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.

Moderate

Is Royal Canin Sensory Smell wet cat food good?

Royal Canin Sensory Smell is a wet cat food rated 1 star, with low ingredient transparency and moderate animal protein content. However, several animal ingredients are described in generic terms, which reduces sourcing transparency. This recipe is free from Gluten grains, Grains (gluten-free), Dairy, Egg, Legumes, Nuts, Poultry, Red meat, Shellfish, Unknown Meal but contains Fish.

Pros

  • Includes plant ingredients that can provide fiber and natural antioxidants.

Cons

  • Relies heavily on animal by-products, which can vary in quality.
  • Uses more animal by-products than muscle meat as protein sources.
  • Some non-animal ingredients are not clearly identified, which reduces formula transparency.
  • Relies mostly on inorganic mineral supplements, which may be less bioavailable.

Tips

  • Protein is Super High (59% dry matter) on our label-based comparison range. Cats generally need more protein than dogs, but diagnosed kidney disease or other medical needs should still be managed with your vet.

    Understanding Super High Protein (≥ 50% Dry Matter)

    Species-Specific Range This bucket uses dry-matter label math. Cats use a higher protein threshold than dogs because cats generally have higher protein needs, so a value that is super high for a dog may only be high for a cat.

    Health Context Matters Healthy adult and senior pets still need enough high-quality protein to maintain lean tissue. Pets with chronic kidney disease or other medical conditions may need adjusted nutrient targets, so those cases should be managed with veterinary guidance.

  • Fat is Medium (14% dry matter) on our label-based comparison range. This is a moderate energy-density signal for many cats, but total calories and body condition still matter.

    Understanding Medium Fat (10% - 16% Dry Matter)

    Moderate Energy Signal This bucket suggests a moderate fat level on a dry-matter basis. It may suit many adult pets when calories, protein, and the adequacy statement also fit.

    Still Check the Whole Diet Fat percentage does not show total calories by itself. Treats, feeding amount, body condition, and life stage can make the same food work well for one pet and poorly for another.

Ingredients Analysis

14 of 14 matched

  • 1 Meat And Animal Derivatives
    Animal Protein

    Description

    Made of unnamed animal parts leftover after muscle meat is removed in the slaughterhouse. It could include anything from necks, undeveloped eggs, feet, and internal organs.

    Why Notice?

    Unspecified animal products from unknown sources. Its quality is highly concerned, often seen in low quality pet foods.

    Uncertain/Risky

    Could be made from any animals, including "4-D animals" (dead, diseased, disabled, or dying prior to slaughter). Contaminated meats can lead to severe illnesses.

  • 2 Fish And Fish Derivatives
    Animal Protein

    Description

    A generic by-product meat meal that does not specify the sources of the fish. It is often made from the residue of animals after removing the parts for human consumption.

    Why Notice?

    An inexpensive, low-quality animal protein source with low digestibility compared to normal muscle meats. By-products are often seen in inferior grade pet foods.

    Uncertain/Risky

    It could be made of parts that are unsafe for humans, such as contaminated dead bodies, which could cause severe illness.

  • 3 Cereals
    Carbs

    Description

    A mixture of grains such as corn, rice, and wheat, usually with a high content of carbs.

    Why Notice?

    An inexpensive filler with gluten, with limited nutrition value to dogs / cats. Made of unknown sources, its quality is highly questionable.

    Uncertain/Risky

    Could be made of by-products / inferior food that are not suitable for consumption.

  • 4 Vegetable By-products
    Carbs

    Why Notice?

    Unspecified plant products made of unknown sources. Its quality is highly concerned, often seen in low quality pet foods.

    Digestion Concern

    A high level of plant-based protein is not easily digestible and offer much less biological value (less absorbed by the body) to pets compared to animal protein.

    Uncertain/Risky

    Without specifying the source, by-products and contaminated plant parts could be used to produce unnamed plant products.

  • 7 Sugars

Tips

  • Some protein sources are less clear: Fish And Fish Derivatives appear near the top without a clearly defined animal source.
  • Plant protein is worth closer review for cats: Vegetable Protein Extracts may raise the listed protein percentage without meaning there is more meat.
  • Higher-priority ingredients to review: Meat And Animal Derivatives, Fish And Fish Derivatives, Cereals.
  • Higher-caution ingredients: Meat And Animal Derivatives, Fish And Fish Derivatives, Cereals, and 2 more have caution notes in the ingredient database.
  • Possible digestion triggers: Vegetable Protein Extracts have digestion notes; watch tolerance if your pet has a sensitive stomach.
