Recently Royal Canin reformulated their Urinary SO formula to contain no wheat gluten and replaced it instead with soy protein. I can report favorable results with the cat insofar as he is eating more without gaining weight as a result of a less filling product and less "thickening" fat from the wheat. Soy protein is an incomplete plant-based protein source, but wheat gluten is a TERRIBLE, irritating non-digestible "filler" source of protein for cats.
So even though pretty much all prescription foods contains really subquality ingredients, anyone know how big of a change up this really is?
