Just to add to Sue’s info, & I’m sure others will have input, from the TR protocol for reducing:
*Alternatively, attempt a reduction when the cat regularly has its lowest BGs in the normal range of a non-diabetic healthy cat (50 - 80 mg/dL) while staying under 100 mg/dl overall for at least one week.
If the reduction doesn’t go well you just go right back to the dose that was working.
If you go to the main page of the Group, you will see this yellow informational stickie:

If you scroll down through the info, you will see the TR Dosing Method with detailed info about holding, reducing and increasing the dose .
