Sorry I missed the tag earlier on yesterday's post about the increase. It's Canadian Thanksgiving weekend, I've been with family.
Unfortunately it's really hard to tell what this dose is doing for Pretty Girl. The depot should have at least six cycles at the same dose for us to say what this dose is doing. But there are a lot of skips and fur shots in there. Not blaming, just saying it makes it hard to suggest what to do because we don't have good data. For now, since you have seen numbers below 150, I would hold the dose as per SLGS.
By the way, you could have shot at least a 1/2 dose tonight, to help preserver the depot a bit. Not all insulin goes to combat the carbs om food. Even kitties who cannot eat because they are getting anesthesia are recommended to get a half dose. Next time Pretty Girl isn't eating what you want, instead of skipping, try a half dose. You probably could have shot the full dose cause she's so high, but work your way up to it.
