If she is above 200 at PMPS, it should be ok to give insulin. I would like to be more conservative, and only have you give her a 0.5U dose tonight.
Here is why:
You skipped the shot last night because she dropped too low on the one unit from yesterday morning. She is really high this morning because of that skipped dose, bouncing we call it. Once you put the insulin into Tashie, there is no way to get it out. She is such a tiny kitty, I think a 0.5U dose is more appropriate.
We can increase the dose after a minimum of 6 cycles or 3 days if the 0.5U of lantus is not working. We will need some test data to determine if that would be a good idea. Would you be able to try for a test tonight just before you head to bed?
We also want to hold the dose to give the insulin depot time to rebuild, refill.
We are trying to find a dose that is low enough that you can give it consistently every 12 hours, no skipped shots.
p.s. I think your SS got messed up a bit. Would you take a look and make and corrections you need to do? Also, for that shot last night that you skipped, please put a zero in the dose column. That way, we know you did not simply forget to update the SS, but did a skip.
