Adrienne, just curious about whether you left food out for Molly to eat in your absence and if so whether she ate it. She was down a tad at +2 but not a lot....and that difference could have just been meter variance. But now we know that if she is down even a tiny bit, she may be having a more active cycle. Take her down to a drop dose tonight. She definitely earned it.
I'm glad you posted and got some help. Those lime green numbers are scary but she was right on the edge of dark green and from my experience, our meters read low at that BG range so it looks a little worse than it is. Many normal cats run in the 40s but we try to avoid letting our kitties go that low when they are on insulin.
She is doing what you want her to do. She is learning that more normal BG is a good rather than bad thing and so her defences aren't kicking in as swiftly or as rambunctiously.
