1 Dehydrated Poultry Protein
Animal ProteinDescription
A dehydrated form of unnamed poultry products, a meat concentrate that could contain 400% more protein than fresh form. Poultry is a generic name that could include any domestic fowl like chicken, turkey, or duck of any condition.
Why Notice?
Often times generic name like poultry is used to cover the inferior meat quality from unknown sources, commonly found in low quality pet foods.
Uncertain/Risky
Unnamed poultry products could be made of "4-D animals" (dead, diseased, disabled, or dying prior to slaughter), turkey, chicken, roadkill, birds, which are not safe for consumption.

Why Concerned?
A common filler without gluten, with limited nutrition value to dogs / cats.
-
3 Corn
CarbsDescription
A grain that is often referred as "cheap filler" in pet foods, mainly due to its high carbs content and low to moderate nutrition profile.
Why Concerned?
A controversial filler with limited nutrition value to dogs / cats.
Allergen Concern
One of the most reported ingredients to be the likely cause of allergies. This could be due to the undiscovered contaminants within corns. Contrary to the real situation, studies show that the chance of getting corn allergy is 14% and only accounts for 3% of allergies.
Digestion Concern
It is high in cellulose, which is an insoluble fiber that is hard to digest.
-
4 Animal Fat
FatDescription
Leftover fat during the production of unknown animal meat meal.
Why Notice?

5 Corn Gluten
Plant Protein ConcentrateDescription
Produced during wet milling of corn by separating protein from the starch. It contains 60% of protein, a relatively inexpensive source to boost up the protein level of pet foods.
Why Notice?
High level of plant-based protein is not easy to digest and offers less biological value. Good quality pet foods should obtain sufficient protein from animal sources.
Allergen Concern
Made with corn, which is one of the most reported ingredients to be the likely cause of allergies. This could be due to the undiscovered contaminants within corns. Contrary to the real situation, studies show that the chance of getting corn allergy is 14% and only accounts for 3% of allergies.
Digestion Concern
A high dose of plant-based protein is hard for digestion and offers much less biological value (less absorbed by the body) to pets compared to animal protein.
-

Plant Protein ConcentrateDescription
Protein concentrate made by removing the starch of wheat flour, it contains around 70% plant protein.
Why Notice?

Frequently asked questions
Is Royal Canin Adult Maine Coon good for cats?
Based on its label, Royal Canin Adult Maine Coon is hard to recommend — it scores 0.5 out of 5 stars on Moesonson’s analysis, with low ingredient transparency and limited animal protein content. Both factors come straight from the printed ingredient list, so review the full breakdown of concerns before choosing it for your cat.
Does Royal Canin Adult Maine Coon contain Dairy?
No — based on the printed ingredient list, Royal Canin Adult Maine Coon does not include Dairy or closely related ingredients, so pets sensitive to Dairy can typically avoid that trigger here. Recipes do get reformulated, though, so re-check the packaging before feeding — Moesonson’s reading reflects the label at analysis time.
Does Royal Canin Adult Maine Coon contain Egg?
No — based on the printed ingredient list, Royal Canin Adult Maine Coon does not include Egg or closely related ingredients, so pets sensitive to Egg can typically avoid that trigger here. Recipes do get reformulated, though, so re-check the packaging before feeding — Moesonson’s reading reflects the label at analysis time.
Does Royal Canin Adult Maine Coon contain Legumes?
Yes — according to the printed ingredient list, Royal Canin Adult Maine Coon contains Legumes. Pets with a known Legumes sensitivity should generally avoid this recipe, or check with a veterinarian first. Moesonson flags allergens directly from the label’s ingredient panel, so this reflects what the manufacturer actually declares.
Does Royal Canin Adult Maine Coon contain Nuts?
No — based on the printed ingredient list, Royal Canin Adult Maine Coon does not include Nuts or closely related ingredients, so pets sensitive to Nuts can typically avoid that trigger here. Recipes do get reformulated, though, so re-check the packaging before feeding — Moesonson’s reading reflects the label at analysis time.
Is Royal Canin Adult Maine Coon grain-free?
No — Royal Canin Adult Maine Coon is not grain-free: the printed ingredient list includes Gluten grains. That mainly matters for pets with a diagnosed grain sensitivity or allergy; most cats tolerate grains well as an energy source. If your cat must avoid grains, choose a recipe without these ingredients.
What are the main protein sources in Royal Canin Adult Maine Coon?
The animal proteins in Royal Canin Adult Maine Coon include Dehydrated Poultry Protein, Hydrolysed Animal Protein, Hydrolysed Crustaceans, but some appear under generic terms such as “meat” or “poultry” rather than by species. Generic labeling lowers the recipe’s protein-clarity score in Moesonson’s analysis, because it stops you verifying the exact protein source — a drawback for pets with specific protein allergies.
