AI ANALYSIS
What MiauMiau's AI actually sees
The protein sources are concerning, with 'dehydrated poultry proteins' as the first ingredient and significant plant proteins like wheat gluten and maize gluten. The high inclusion of maize and wheat, along with vegetable fibers, indicates a substantial amount of low-value carbohydrate fillers for an obligate carnivore.
According to MiauMiau's analysis of over 2,700+ dry food products, Royal Canin Gastrointestinal Hairball scores below the dry food average.
