Cathy, would you list some of the foods you like that are comparable quality?
The Flint River Ranch is $1.20/lb. to my door. Nutro Natural Lamb Meal and Rice is about $34. per 40 lbs. local plus 8% Texas sales tax = $0.92/lb. to my door.
The following link is to ingredient lists, it shows Diamond Lamb but with the next 3 successive ingredients as grains so you may be paying for mostly cereal.
It does show Innova to have its top ingredients as meat or meat meal, so although outrageously pricey, it seems to stand up to the competition where it counts.
