That depends on which dosing method you eventually decide on. When following SLGS, you're looking for nadirs (the lowest point in the cycle) to be between 90-149. Sock's aced it today!
In the beginning, a lot more testing is requested. Reason being that we are trying to get a sense of (from
Sticky- The Basics: New to the Group):
"Learn how YOUR kitty is responding to insulin:
- Onset - the length of time before insulin reaches the bloodstream & begins lowering blood glucose
- Peak/Nadir - the lowest point in the cycle
- Duration - the length of time insulin continues to lower blood glucose"
The Stickies at the top of this forum page explain the differences between the two approaches towards regulation. TR is a more aggressive approach in that the desired nadirs are 50-80. That can be a bit scary at first especially when you're trying to learn the lingo here, testing, food, onset, nadir, duration, etc, etc, etc. It is also a published protocol. The links can be found in the
Sticky- Dosing Methods.
TR also requires
at least one test each cycle in addition to the AMPS and PMPS.
The reduction point when following TR is once under 50 for a newly diagnosed diabetic cat (less than one year) (can be very scary at times) or one week in greens.
Doses are held for 3days (6cycles)- 5 days (10cycles) before evaluating nadirs to determine an increase.
Those are just some of the major points off the top of my head and I know that there are more. ASK ANY AND EVERY question that comes to mind!! Even if you think you know the answer, ask anyway

. There are many members here to lend their support.
The most recent convert from SLGS to TR that comes to mind and also a very newly dx kitty is

In any event, I think you should hold this 0.5 unit dose unless the numbers start trending otherwise. I'm hoping it will be a dose that you can shoot twice a day. There's no rush in making a method decision just yet
