I looked back to see if you ever gave any history on Zed; for example, do you have an idea of how long he might have been diabetic before you started insulin? I’ve seen many members remark that, looking back, there were signs but they didn’t think about diabetes. Also, how was his starting dose determined and what is his ideal weight? Is he underweight and, if so, what is his weight? Depending on his weight, your vet might have been right about the 3u but I’d need to know his weight first. If that was the correct starting dose, then you are likely dealing with some
glucose toxicity and insulin resistance.
He does not appear to be overdosed even though you have gaps in testing which has already been discussed. It’s really important that, going forward, you know how low a dose is taking him before you increase. To do that, you will need a couple tests at night like a +2 and a before bed.
You want to be sure that you don’t hold onto doses too long when you’ve got data. I would not have left him at 1.5u for such a long time. Not a criticism....just an observation.
I’m glad you increased to 1.75u but I would not change the dose again immediately. What you can do, if all you see is BS
above 300 is increase by 0.25u after four cycles or by 0.5u after six cycles at the 1.75u dose.
And you aren’t a “PIA”. No one likes to see their kitty in higher numbers. Pls tag me if you have questions.
