I have a diabetic kitty, Morgan. He started at 8 units of insulin once a day and then went to 5 units twice a day. His food was changed to Purina DM (diabetic management). It took about 7 or 8 months, but gradually he was weaned off of the insulin. He's been off of it for over a year and a half now. I strictly regulate the amount of food he gets. In addition to the dry DM, he also gets a pinch of canned food in the morning and the evening. He always had his morning treat, but the evening was added when he started to get the insulin shots. He didn't mind the shots since he knew he was getting his canned food as well. In fact, he'd come and remind me when it was time. He still does. LOL I know that each cat is different, and Morgan's case isn't the norm, but I just wanted to let you know that diabetes can be managed. In fact, it's easier to do in cats than humans, because we can make sure they don't "cheat". Also, in case you haven't found it yet, here is a link with lots of helpful information about protein vs carbs in all different kinds of cat foods. Keep us posted!
