I have a cat who was recently diagnosed with Diabetes. The vet wanted to start insulin right away but they also gave me the option to try a change in diet as he was on dry food with a very high carbohydrate component. The vet was not confident it would do any good. When tested he was 25.3 on our human glucose meter. He has been on a strict diet and in one week has dropped to 19.1. My question is what number do we need him to hit to define the change of diet as a success and forgo Insulin? Also any advice would be sincerely appreciated.
