Oh Beth, how wonderful that you fostered those rescue kitties for over 2 years. That had to be so hard to let them go even if it does give them a better chance to find a loving furever home together. I don't know how you do it. I'd be a basket case or I'd just end up keeping them.
Poor Chris! Tooth reabsorption in cats is so sad but we know he is getting the best of care under your watch!
So glad to hear Buddah Kitteh is holding his numbers well and that you are finding the willpower to put the meter down. It's tough breaking a habit even if it's something you are happy you don't HAVE to do.
Do you think Elmo is sleeping more now than when he was on insulin? I wonder if having his thyroid meds up to full dose and seemingly working well has anything to do with this. Or maybe he's just not on alert all the time wondering when his Mama is gonna come and poke him!

If his appetite is Ok and there are no other issues, I don't think I'd worry too much but then I have an 18yr old who basically sleeps the day away so maybe my take on this is off base in Elmo's case.
Your question about teeth cleaning is a bit of a conundrum and one I am currently wrestling with for my 18yr old. I understand not wanting to stress Elmo out with a vet visit all too well. My guy turns into a Tazmanian Devil at the vet and has to be sedated just to be looked at. I think though if Elmo is healthy enough to have his teeth cleaned, it might be worth it just to avoid an infection which is harder on an older cat and could knock him out of remission.
As for feeding or not feeding overnight, you could do a trial run of not feeding him one night and see what his number looks like the next day. I think this boils down to whether Elmo's pancreas is pumping out insulin throughout the day/night or more pulsative around mealtimes. If you are getting up to feed him at 4AM, you could freeze some food in an ice cube tray and leave it out for Elmo to eat when it thaws so he can eat if and when he gets hungry and then Mama can get her beauty sleep.
This new path called Remission is going to take some adjustment. I remember the first time Menace gave me a blue number and I was happy but a bit scared. Then came that first green number and yikes did I panic! Now even lower than I'd like green numbers are second nature and there is no panic....just action because I know my cat and am confident I can keep her safe. Remission is much the same....not as much work but it still takes some time to get used to it. You and Elmo will adjust soon.
Heck I'm still dealing with Beth/Elmo withdrawal so we all got some adjusting to do.
