AI ANALYSIS

What MiauMiau's AI actually sees

This is a prescription liquid diet severely inappropriate for a healthy obligate carnivore, with water as the first ingredient and maltodextrins (a rapidly digested starch) as the second. The formula is dominated by plant-based proteins (soy protein, maltodextrins) and delivers only 30.6% protein on a dry matter basis alongside an estimated 46.5% carbohydrates, while also containing carrageenan and modified corn starch.

According to MiauMiau's analysis of over 5,000+ dry food products, Royal Canin Feline Renal Support Liquid scores below the dry food average.
