If he gets through the trial successfully, you enter a new phase. Your cat is still diabetic, but has now become diet-controlled. Continue feeding low-carb food and small meals for the rest of his life. Avoid medications with sugar in them and steroid medications unless they are medically essential. Continue testing blood sugar weekly for the next few months and then monthly forever. It's a good idea to weigh him monthly. His weight should remain stable. If he seems "off" or sick, or is showing symptoms of diabetes (excessive drinking, eating, urinating, weight loss) test his blood sugar right away. Keep the teeth clean; dental issues can bring a cat out of remission.
If you see rising blood sugar numbers, post here before you restart insulin and ask for advice on how to proceed.
