Would you note that on your spreadsheet by either stacking the #s all in the preshot column like this:
+12 = 131
+13 = 174
+15 = 378
then nothing in the rest of the pm cycle column and a note in the comments saying "Shot 0.25u @ +15 and 0.25u at +6"
Or writing a description of what happened in the comments column.
Looks like he took it all fine, but just make a note to not shoot at less than 12 hour intervals if something like this happens again. The reason is that if shots are given too close together, you could overlapping action between both shots and that could cause lower numbers than you would otherwise expect.
For now, though, all is well.
You probably want to go back to 0.5u that you meant to be at now, and hold that dose for a few days unless he goes low enough to have his dose reduced, depending on which dosing method you want to follow. Lantus works best when the dose isn't changed too often.
You are blessed to have an animal soulmate! If you were already close, dealing with his diabetes will bring you closer than you can ever imagine. It's a crappy disease, but it does have benefits in how closely bonded you get with your cat. It's pretty amazing how in tune one becomes with our diabetic cats.
