Feeding low protein food at early stages of CKD is the old school of thought. Newer research shows that it's more important to restrict phosphorus than protein. So you want to feed a low carb, low phos (less than 0.5% on a dry matter basis). Low carb is good for diabetes and controlling the diabetes helps the CKD by reducing the strain on the kidneys. Weruva have many low carb low phos options.
