Is there anywhere on the boards you post regularly to link to previous condos? I didn't spot your insulin, what do you use?
Some things I notice:
* You are often giving high carb treats on any green number prior to the high numbers. The greens are probably contributing to the bounce, but those high carb treats may also be why you are seeing high numbers. Usually we only resort to high carb when we get low numbers that are early in the cycle, like +1, +2, and are down in the 50s or 40s and below and just feed low carb food to flatten or "surf" those nice higher greens. Without knowing your history or kitty, is there something other than nerves that has you giving high carb treats on the higher greens at +4 and later in the cycle?
*You have been adjusting the dose. If you are using something like Lantus, it reacts best with consistant dosing. Unless we see an unsafe preshot number, we try to keep the dose consistant for a number a cycles to let the dose settle. The reduction in a dose in the PM could lead to a high AMPS number.
The liver most likely is responding to those low numbers by spilling sugar in a protective measure and that's what we refer to as bouncing. It will help to try to get everything else consistant, find a dose you are comfortable shooting all the time. No high carb unless you see a number under 60 or a really early cycle large drop that you can't monitor or something, but keep the high carb to the more emergent situations and see if you can stabalize everything.
Again all this is without knowing if there is something in the history of your cat that make the good green number more dangerous. For most cats 60-100 are really nice mid-cycle numbers to see.
As the diabetes gets regulated, if you are feeding a wet food diet that dander should clean up nicely.
