Hi Stephanie!
I'm glad to see you, and Kale, in PZI.
Jenn asked you a good, and very important question. Did you get new syringes with the Prozinc? If not, not a big deal, but we need to know that so that we can make sure the dose is right.
Like others already said, we usually like to start at 1u. Kale has actually had much better numbers the past two days on a dose lower than 2u of Humulin. Your Humulin data looks different than most other cats I have seen on Humulin. It seems to have lasted longer than normal with Kale, which can be a sign that the dose is too high. Usually it only lasts 8 hours or so, with the low point around 4 or 5 hours after the shot. Looks like Kale has been going lowest a little later than that.
For those reasons, I think a starting dose of Prozinc of 1u makes sense. If you try that for a couple of days, and the numbers get worse, it's really easy to increase in small increments to find a better dose.
We normally advise people when increasing to only do so in .25u steps. It could be that his "right dose" is someplace between 1u and 2u, and if you just jump over the right dose, it's harder to find it later. What can happen is that if the dose is too high, the numbers will get higher instead of lower, and it would make you think that more insulin is needed, when the opposite might be true. It's sounds confusing, I know!
How long has Kale been on the FF classics?
