hi john. i understand you've been concerned about how much apollo is eating despite the fact that he hasn't lost any weight. you do realize not every cat eats 5 - 6oz. a day, right? some kitties maintain their weight on quite a bit less. as long as apollo isn't losing any weight, i don't think the amount should be of concern.
have you given any thought to restarting insulin at 0.1u:

while his numbers are looking good it might be a good idea to pull them down a little further in order to give him a chance at a strong remission...
just my thoughts...
