for that matter could be a combination of both -- these are extraordinary circumstances -- not what you'd usually do
can't really give advice, merely tell you what I do -- (in the evening)
between the PS mini meal/treat and the actual meal at shoot time, Catcat gets a reasonable amount of food, say 2/3 to 3/4 of a 5.5 can
then a heaping tablespoon of food at +1 and +2 -- if I feed him more, he'll pig out on it
this is a small enough helping that it doesn't affect the later test greatly -- just slows the fast-acting insulin down a hair
if I could, I would put off the test until +4 but that's pushing 11 pm and I'm tired and shaky, so he gets a slightly bigger helping (1/3 of a FF can or 3-4 tablespoons of a larger can, plus the no-carb treats because that's when I test for the night .. if it's unusually low I know I'll have to follow up later (so far hasn't happened)
from my own experience as tending towards hypoglycemia myself, I know I need to eat some protein about every 3 hours
cats' metabolism is about double mine
so small meals every hour to hour and a half, helps keep the body more stable, less highs, less lows
this also encourages pancreas, if it's functioning at all, to release small amounts of insulin more frequently
may "train" the liver not to dump scads of glycogen in as a "lifesaving" measure, if the BG is more stable
(that's what a bounce is, the liver is pulling stored glucose out and dumping into bloodstream) == simplifying it but that's what we understand)
and as you can see from the spreadsheet, I'm still chasing the correct dose -- enough that he gets into the lower blues if possible, not so much that he hits nadir in the middle greens (at least for now) -- maybe later we can lead him towards more green, less blue, only occasional yellow
and I'm at +4 -- actually a few minutes late, gotta do the test, then because Im having trouble keeping eyes from drifting shut, I will leave with the very best of wishes
