I’m kind of starting to wonder if toxicity has already happened. She was diabetic long before I caught it. Bad Mom I know but hindsight is 20/20
So I see Gretchen was in the 500's again this morning.
Do you think Gretchen got into any contraband food overnight? Dog food maybe?
If not, then maybe it's time to "start low, go fast" ... Or at least a
little faster. I'm NOT a fan of being aggressive when you can't get mid-cycle tests BUT I think we need to get her out of these blacks. Given the data you have on Prozinc and its typical nature, I agree with the others that you're probably not at high risk of hypo the way you might have been on N... at least not right now. I don't personally like making assumptions (too easy to get in trouble doing that!) but you now have some history on Prozinc.
So given this morning's black, I'm going to reverse myself and say that I think it makes sense to step on the gas a little. I wouldn't "floor it," lol, but you've been patient and done your best to go slow and make sure you're being methodical. Kudos for that. My opinions are evolving based on the data and also the fact that Gretchen had likely been diabetic for quite some time before you caught it, which I didn't realize. You probably
do have some glucose toxicity going on at this point, but it is what it is. It's unfortunate but not necessarily catastrophic.
Did you give 1.5 or 1.75u this morning? I wouldn't be surprised if you did the latter, given the black. I personally would go to 1.75 today and tomorrow, run a curve on the 1.75u on Friday when you're off, then if numbers are still high, maybe go to 2u over the weekend and get some data on that dose.
Sometimes my guys would give me a quick response to the dose change and drop down into better numbers, only to then settle back into higher numbers. Other times it would take time multiple cycles to see the full result of a dose change. Every cat is different, but the data will guide you as you learn Gretchen's idiosyncrasies.
Just remember that dental issues, contraband food, UTIs, etc can inflate BG, so if you think you have any of those things at play, you might want to keep it on your radar to address them. And please do check for ketones.
BTW, I wouldn't increase the dose every 3 cycles because you'll be doing multiple increases with no mid cycle data whatsoever. But I'd consider maybe every 5-6 cycles so you can "time" the changes so you can maximize the value of the data you collect on your days off.
Again, just my two cents.
(For those who don't know me, I happened to pick up on the "fur shot" drama over on Health awhile back so followed bobbi and Gretchen over here)
