Ingredient concerns

• Corn Gluten Meal (medium concern): Primarily used as an inexpensive plant-based protein booster that can inflate the protein percentage on guaranteed analysis without providing the complete amino acid profile of animal proteins. Its presence in large quantities may indicate the manufacturer is supplementing with cheap protein instead of using more meat.
• Chicken By-Product Meal (medium concern): While nutritionally adequate, by-product meals can vary widely in quality and digestibility. They include parts like necks, feet, and intestines, which some consumers find objectionable. Quality control is less consistent than named muscle meat sources.
• Soy (medium concern): Soy is a common allergen in dogs and cats. It contains phytoestrogens that may affect hormonal balance, though the clinical significance in pets is not fully established. Often used as an inexpensive protein and carbohydrate filler. Most soy in pet food is genetically modified.
• Caramel Color (high concern): Certain classes of caramel color (Class III and IV, produced with ammonia or ammonia-sulfite processes) contain 4-methylimidazole (4-MEI), which has been classified as 'possibly carcinogenic to humans' (Group 2B) by IARC. California's Proposition 65 lists 4-MEI as a carcinogen. Like other color additives, it provides no nutritional benefit to pets.
