Or try testing a civie, that can help you know how the meter reads for cats. I can't imagine though that her BG would change 60 points in 4 minutes...? If it were me, I would probably want to try another meter. For the moment though I don't think it's a significant problem - any way you look at it, the #s are still too high. But for when you do see better #s (and you WILL!!!

), you will want a meter you have confidence in, at least some confidence, LOL, since they all have a pretty wide error margin. ohmygod_smile
As for the #s, I think you need to put "It's a Marathon, not a Sprint!" on your fridge, LOL. :mrgreen: As I understand it, the typical cat takes weeks to get good #s on Lantus. My understanding could be wrong, but that's what I would anticipate. If she does better faster, YAY, but if not, at least you will be prepared for the longer haul. When you are posting on Lantus, be sure to tell them how she is feeling, etc. There are things that can be done to reduce the #s faster (like a fast-acting insulin), but you probably don't want that unless it's needed. If she is doing ok, then no worries, just stay the course and trust that the better #s will come when they do.
If she is seeming unwell, make sure people know that, and ask if there is anything safe that you can do to speed things along. That's what I'd do at least.

Given that you weren't seeing the #s drop much on PZI, my guess would be she may need several dose raises on Lantus before she gets to good #s, she may just be a kitty who needs more insulin that some cats, no shame in that. I would ask people to look at her PZI SS and tell you if you need to adjust your Lantus approach at all, or just wait it out (if she is feeling miserable that is - if she is doing fine, then you are good!).
