Hi, Carol and welcome to Lantus Land.
One suggestion right off the top would be to use one meter. It looks like you alternate between an AlphaTrack and a Relion meter. It looks like you know that the AT reads 30 points higher than a human meter, which is good! Sticking with one meter will make it easier for you (and us) to be sure whether Oreo needs a dose change and reduces the chance of an error. I'd also encourage you to get at least one test in addition to your pre-shot tests, each cycle. Lantus dosing is based on the lowest point in the cycle (nadir) which is usually somewhere toward the middle of the cycle. Pre-shot numbers are helpful with respect to whether it's safe to give a shot; dose reductions are based on the lowest number in the cycle.
If you're opting to follow the Tight Regulation Protocol, you wouldn't reduce Oreo's dose unless numbers drop below 50 on a human meter or 80 on the AT. You may want to take a look at this post on
how to handle low pre-shot numbers. Skipping the shot is one of several options -- although I agree that skipping last night may have been a good idea.
I'm not sure if you're asking if you should shoot late. If your schedule can accommodate a late shot, it's fine. However, you need to consider that your PM shot will be 12 hours from when you shoot this morning. For most people, if you are more than 2 hours off schedule, it's hard to adjust the time and they'll skip. What I would point out is that it looks like you were comfortable shooting a 199 yesterday morning. The 176 today is pretty much the same number. (There's 20% variance in any test due to meter variance.) That said, it takes a bit of time to get comfortable with shooting lower numbers. We also don't tell you to shoot and then abandon you. Rather, there are lots of people here with experience in managing lower numbers (and there are
written guidelines) who will stick with you and help you should Oreo's numbers drop and you're not sure what to do.
I also would point out that not every cat experiences big changes in BG numbers due to taking a steroid. Whether or not the prednisolone effects Oreo's numbers really isn't an issue. For anyone who's cat is dealing with medical issues, we work the insulin dose around the other health issues and other medications.
I'd encourage you to look over the starred sticky notes at the top of the board. They will give you a solid foundation in using Lantus to manage Oreo's FD. Please let us know how we can help!
