My Vet told me five days ago that he has diabetes. I notice weight loss and not eating the last few months. Never did I put two and two together with diabetes. He was 23 pounds during the winter, he is a big cat, and is now down to 16 1/2 pounds. This Monday got him in and did the blood work and so on, and found out his glucose was 400, but should be 100. My Vet said that he might not have to do insulin by changing what he eats. He's on a high protein, no carb diet, using Sheba whitefish and tuna. I worry about protein, fat and carbs, Sheba will not let this information out. Does anyone out there have a good wet food for a diabetes in cats?
