Cassis,
I recognize the unrest you have about your kitty's response to insulin, because I have it myself. You can drive yourself crazy. Ask me how I know that.
In many cases, I've had to admit my expectations for consistency are too high. The bottom line is we do the best we can with the tools given, and some days it JUST does not feel like enough.
There are SO MANY factors that influence what a cat's blood sugar does. The dose given (even if perfectly and exactly the same amount as given previously - which it never is) will not be absorbed in the same way, nor will the cat's metabolism be the same, day to day. I *really* don't think your insulin is unstable.
I totally understand your concern about being high BG and its effect on the kidneys. I share that concern, for my cat. Hard to not be frustrated, I know!
So, kitty beta cells, liver, pancreas and intestines are all doing a little waltz... And the amount and TYPE of food, pH of stomach acid, cat's activity level... I could go on & on... these will all affect the readings you get. Switching carbs from 4 to 10% is a relatively large move. And it reverberates in the cat for more than just a few hours after the meal.
I fed my kitty the exact same weighed meal twice a day for many weeks, trying to eliminate that variation. It may have helped, but didn't get us where I wanted to be. There was still a lot of variation in his numbers, at the exact same dose.
In addition there are factors like Prozinc being a suspension, so mixing it *perfectly* is impossible. Rolling the vial gently for a minute is the best you can do. Then, the small amounts we try to inject into the cat repeatably is a battle, too, even using the smallest syringes with the most accurate markings. Please realize you might see variation even after a week of exactly 4u twice daily, even on the exact same meal.
And there is the undeniable factor that diabetics really do need to "settle in" to a dose. Some more than others, but for all kitties, there must be patience doing the same thing (as much as possible) day after day, for many cycles at a given dose. Please realize seeing variation in response is normal. Normal.
It's hard for all of us.
My struggles went on for months, and Sue and others in this forum were great at helping. But we had trouble increasing dose because a SLIGHT change (from 2.0 to 2.2 or 2.4) was too much. But 2.0 u (or even 2.2u) was usually not enough. He stayed high.
From your sheet, it looks like you will have room to go up on dose... so let others help you do so, slowly, based on data you get for your kitty's BG.
The specialist I just saw with my cat made me realize how complicated this all is. Every cat is different (ECID!) and it will be several more weeks/months of dosing and watching glucose readings before you really understand your baby.
Sue and others in this forum will help you as you begin to see patterns and begin to know what to do... They have many years of experience, and helped ME set my expectations more realistically. You're at the very beginning of this journey. And you are doing the best you can, and it is enough.
Good luck and keep testing!
