Hi Barb,
In your PM today you asked what I had meant when I asked someone this in another thread some time back:
Did you ever do that "feed, test an hour later for a rise, then a couple hours later to see if she was dropping on her own" thing?
That is something that people can try when they are seeing low preshots and cycles, but aren't quite sure if kitty is ready to go off the juice. Sometimes, people will do it when they are doing the "OTJ trial". The intent is to see how well the kitty manages his or her BG on their own, with no shot given that cycle.
What you do is test like normal, but don't give insulin. Then you feed like normal. You then get another test at +1 or so. That test should show you a higher BG, which would be caused by the meal that you just gave. After that, you wait another 60-90 minutes, and test again. What you hope to see is the BG has dropped. That would indicate that the pancreas is doing the job nature intended. Maybe not 100% of the job, but it is producing insulin, and kitty's cells are absorbing blood glucose for energy like they are supposed to. That causes the BG to go down, because the glucose is being used by the cells instead of staying in the blood. Your curve might look like this:
AMBG 160
+1 200
+2 180
+3 140
etc.
If you normally feed mid-cycle, you could get reading before, and after that meal or snack and hope to see the same sort of rise and fall.
You would hope that it just stayed right around that level or dropped for most of the cycle. It might come back up to 160 or higher by PMPS, or it might not. If it stays pretty much level, then that is fantastic news. Because even though the numbers are still a little above the normal range, at least his body is maintaining some measure of control, and trying to self regulate.
At that point, you are pretty much into the mini/micro dosing phase, and the cat is almost ready to go off of insulin. At the same time, you can tinker with feeding timing in order to spread the BG boost from eating more evenly, which will also help out the pancreas by making the need for natural insulin more consistent, without peaks and valleys.
Hope that explains it...
