You can use wet food in those timed feeders. I understand they have little ice packs, underneath. Even if those feeders don't have ice packs, the food will stay fresh enough for a good 6-10 hours. More if you add some water to the food to keep it moister.
With Logan being timid, he'd probably be scared of the sound the timed feeder makes when it opens. It's something you'd have to get him used to.
There are also microchip feeders, that only work for a particular microchip, the one it is programmed for.
Plus with all your other cats, Logan would have to be sequestered in a separate room. He'd probably hate that though.
It's possible the large amount of wet food caused his BG's to go up so far at +8. But more likely the cause is from the insulin being mostly used up by that time, and a natural rise in the BG level occurred. Certainly looks like the +9 of 228 is a bit of a bounce from those low greens today.
Is there anyone else that lives with you that you could teach to home test? Or someone in your "bubble" that you would trust with Logan, and someone that Logan isn't scared of, someone he would not run away from and hide?
The lowest a glucometer will read is LO. In other words, too low to measure. Some meters read all the way down to the low 30's. I'm not sure how low your meter will measure.
DOES THIS EvER GET EASY???
Some days are easier than others. Some days, much more difficult.
Those lower BG's earned Logan a dose reduction to 0.75U. But if you don't think he'll hold it, then stay steady at the 1U. If Logan were my cat, I'd reduce and then see what happens after the bounce clears.
