Does Young Again qualify as a high protein, low-carb cat food for diabetic cats?

Yes. Our entire line of ZERO cat foods are perfect for diabetic cats. And, it can and should be fed to all of your other household cats. Cats are carnivores and have no nutritional need for starch/carbs. Other pet food companies will try to convince you that a starch/carb content less than 10% is fine for a diabetic cat; don't believe it. Our 50/22 formula contains less than 6% starch and we would never recommend feeding it to any diabetic cat. As much as 6% starch in a cat food will drastically reduce the remission rate for a diabetic vs. a cat food with less than 1% starch.
