That was a great stretch of blue there. I would hold the dose one more day (total of 8 cycles) to see if she can see even more improvement. If not, then I'd go up to 9 units. I like seeing the improvement in her spreadsheet.

You are seeing more yellow preshots and more frequent blues.
When you talk to the vet next week, I'd highly recommend you get them to test her for high dose conditions. The
IAA test is for insulin auto antibodies and the
IGF-1 test is for acromegaly. The blood is sent to Michigan State University, the only place in North America that does those tests. We have a number of kitties with one or other or both of those conditions here. Usually when kitties are on low carb wet food or raw, and have been increased methodically (as you have done), then there is usually a high dose condition present. FWIW - I didn't bother seeing a specialist, I got my own vet to run the tests. Seeing an internal medicine specialist once you have those test results might be more productive.
