Frequently asked questions
Is Royal Canin Adult Persian good for cats?
Based on its label, Royal Canin Adult Persian is hard to recommend — it scores 0 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 Persian contain Dairy?
No — based on the printed ingredient list, Royal Canin Adult Persian 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 Persian contain Egg?
No — based on the printed ingredient list, Royal Canin Adult Persian 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 Persian contain Legumes?
Yes — according to the printed ingredient list, Royal Canin Adult Persian 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 Persian contain Nuts?
No — based on the printed ingredient list, Royal Canin Adult Persian 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 Persian grain-free?
No — Royal Canin Adult Persian 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 Persian?
The animal proteins in Royal Canin Adult Persian include Chicken By-product Meal, 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.
