Hopefully her appetite will be back by lunch. I do really worry about DKA with our kitties in higher numbers, but I understand how expensive those meters can be!
@Diana&Tom, I wasn't totally clear on when the 12.2 happened. It's on the spreadsheet at +11, so I thought it was a bit before the usual shot time? If it was 12.2 at shot time, then yes, she would have been fine to give the dose at that number. When someone is nervous about dosing though, sometimes waiting to see the rise makes them feel safer about giving the full dose. For new folks who aren't quite sure about getting BG tests during the mid-cycle, we say the cut-off on a human meter is 11.2/200. However, once someone is comfortable with getting mid-cycle tests, they can and should shoot below that number. And especially when you have a cat who still has a nadir as high as Josie's. There is a big enough cushion that she could shoot that low and keep her safe. Prozinc is much more stable than Caninsulin.
If she shot on a lower number, it
might hold the numbers down throughout the cycle, however given how high Josie is right now, more likely she would spike during the two hours before onset and it wouldn't make much difference just yet. Once she starts getting into some better numbers in general, then you are exactly right that shooting on the lower PS numbers is how you hold the whole cycle down. So shooting the lower numbers (with monitoring) becomes a very very important part of making progress with all of this.
Great question! Thanks for asking!
And just to clarify for anyone lurking: by "lower number" I mean "lower than usual number". I'm not suggesting she give a shot if her kitty is in the greens!
