Thanks for the clarification.

Just wanted to make sure what my reference range was when looking at your numbers as a human and a pet only meter are calibrated differently.
One thing to keep in mind when working with either of the L insulins is the dose you just shot isn't the dose they are using during that cycle. Since Lantus is a depot insulin it forms crystals under the skin that have to dissolve before the cat can use them to pull down blood sugar that is why it is so critical to have the dose stay the same, unless things like kitty is sick and not eating well or not keeping food in the tummy because they are vomiting. So you did good there. Hypos are only scary until you've walked through one, but they are something to be vigilant against. And yes, you never want to leave them alone if you think they might be headed into that territory.
Actually she doesn't look all that bad from what I've seen on her spreadsheet. Especially for no longer than she has been on Lantus. My suggestion at this point would be keep her on the 2u for several days and try to get as many spot checks as you can especially in that +5-+7 range so we can see just about where she nadirs, if you can get a full curve in great but if not just a few random spot checks and try to vary the times which will help fill in the picture.
Other than that, keep posting and keep asking questions as I'm sure we will have a few more for you as well as we think of them.

And we will all put our heads together and see if we can't get her at least regulated for you.
Oh YES!!! They are our furry loves here. Or as I tell people they aren't cats they're tiny people in cheap fur coats. :lol: I promise we will do everything we can to help you help Emma.
Mel, and The Fur Gang (yep all those names in my sig are my furry babies)
