You were very lucky Marley didn't develop DKA.
Cats don't get some of the things humans do but DKA can kill them much quicker.
@AnneforMarley Looking at Marleys SS......to get a strong remission you need to give insulin for as long as you can if the numbers are up a bit higher than normal. Normal is 50-120.
Anything above 120 is above normal and it is best to have the numbers under 100.
There are doses lower than 0.25.
There is 0.1units and a drop of insulin.
If you would like any help please post and we are happy to help you.
I would test at the normal preshot time both am and pm at the moment. If the number is over 100, I would test again a couple of hours later to see if it has come down at all.. otherwise test at the next preshot time.
I see you gave some higher carb food in the evening cycle of 3/11 at +3 (or +15 really as no insulin was given for the pm dose)
If you are not giving insulin, a number like 63 is normal and does not require higher carb food. If you wanted to feed him something, give him some normal low carb food.
