My approx. 10 year old cat has been diagnosed with diabetes. It has been suggested that he go on insulin, however I'm not sure if I want to go through with that. We have switched his diet to Nature's Variety canned food as I have read that he should be on a low-carb diet and that was the lowest carb food I could find. His blood glucose level has lowered 3 points in about a month since the switch.
Any one else out there with a kitty with diabetes? Is there anything else I can do for him at this point?
