We recommend that insulin be given until the need is no longer there. If you can't afford insulin there are some other things that you can try to see if it helps. Dia-IonX was designed to help with the symptoms of diabetes and to stimulate the body to heal. In the cat there are factors that help them to respond well to therapy. It is important to feed wet cat food and no dry food at all if possible and all foods including treats should consist of ingredients suitable for a diabetic. You could ask your veterinarian about feeding canned DM by Purina. If your cat won't eat it I can suggest some other foods that are low in carbohydrates. In addition, I give digestive enzymes, probiotics and fish oil. Dia-IonX helps the body to better utilize the diet and supplements better for a synergistic effect for faster healing. It is also important to avoid giving water that contains chlorine and fluoride.
Exercise helps to move glucose from the blood stream into the muscles helping to regulate the blood sugar levels. Hopefully you can get your cat to play. Having a consistent schedule is necessary in good regulation.
