Actually, instead of just skipping, I'd rather we did a "food test" to see if his pancreas is working.
So, no shot, but go ahead and feed. Test again in an hour (he should be higher from the food) and then again in 2 hours (the food should have cleared his system by then). If his number from 2 hours is around 130 still, then we know he's got some insulin his body is producing. If his number is significantly lower than 130, then we know his pancreas is producing quite a bit of insulin, which is a fantastic thing and a sign he's trying to go into remission.
