I agree that some of the prescription diets are very helpful. But to get a prescription for a food for weight reduction, I just have a hard time understanding why nutrition is not used more by vets. My vet said Hills teaches or provides the material for their classes and the class time is minimal. I don't remember exactly.
I copy/pasted the ingriedents from Sci Diet Feline r/d.
Chicken By-Product Meal, Brewers Rice, Corn Gluten Meal, Powdered Cellulose 18.8% (source of fiber), Chicken Liver Flavor, Soybean Oil, Calcium Sulfate, Potassium Sulfate, Choline Chloride, Vitamin E Supplement, Taurine, Glyceryl Monostearate, Iodized Salt, vitamins (L-Ascorbyl-2-Polyphosphate (source of vitamin C), Vitamin E Supplement, Niacin, Thiamine Mononitrate, Vitamin A Supplement, Calcium Pantothenate, Riboflavin, Biotin, Vitamin B12 Supplement, Pyridoxine Hydrochloride, Folic Acid, Vitamin D3 Supplement), Potassium Chloride, preserved with BHT, BHA and Ethoxyquin, L-Carnitine, minerals (Ferrous Sulfate, Zinc Oxide, Copper Sulfate, Manganous Oxide, Calcium Iodate, Sodium Selenite), Beta-Carotene.
I just read that "powdered cellulose" is fiber that traps moisture. Does this mean the pets eating this need to be watched for dehydration or urinary problems? Hills did mention urinary something at the bottom of the ingred page. This could be important with all the renal problems after the recall.
Sorry, I do wonder about this because my dogs were on the canine r/d for years per vet request. I only startted paying attention to nutrition after the recall. Guess we all got paranoid. Good luck with the weight loss.
