What are the main protein sources in Royal Canin Gastrointestinal Fibre Response?
The animal proteins in Royal Canin Gastrointestinal Fibre Response include Meat And Animal Derivatives, 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.
