Hi. I'm a kittymom but my kitty has heart disease not diabetes. But I am catsitting my grandcat who is diabetic. He is constantly starving and managed to get into the cabinet and knock the cat food onto the floor while I was gone for a short time. Apparently he had a great time. I know hypoglycemia is dangerous, and having had some experience with it I think I would recognize it. But I don't know what to expect or look for if he pigged out. He is pretty well regulated, and had just gotten his evening insulin shot. Should I watch him all night? and what am I watching for? I don't have a glucometer here but will certainly have my son bring one tomorrow. Am I right in thinking this is not as bad as a severe blood sugar drop? What would constitute an emergency?
