Until you test the urine or blood for excess sugar you do not know whether or not your cat has diabetes. Kidney disease or cancer can also cause similar symptoms. I would recommend that you get a diagnosis.
Dia-IonX was designed to help with the symptoms of diabetes and to stimulate the body to heal. It is not recommended to use it alone in the initial stages of diabetes. However, 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. 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. Dia-IonX also contains homeopathics that benefit the kidneys. 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.
