While I appreciate that
@Nancy29 took the time to share her experience I have a few concerns and frankly am quite alarmed with a couple things she has stated.
To start with we don't know if she checks the BG to see if it's even high enough to shoot and we can't see a spreadsheet to see what she's talking about.
A cat staggering around sounds more like a hypo symptom from too much insulin.
There are a number of ways to interpret this statement. The first that comes to mind, too high of sugar could be from bouncing caused by the BG going too low which could possibly mean the dose is too high. We just don't know what's going on without seeing a spreadsheet.
@KittyKatMama you're still in the process of collecting data. While it's best to stick to an every 12 hour dosing schedule, sometimes real life gets in the way. Prozinc does have some wiggle room when it comes to shooting a little early or a little late, within that hour window if needed - as long as the BG is high enough to shoot you can get back on schedule pretty much right away.
It's all about the data and how your cat responds - ECID (every cat is different).
Yes, it's important to withhold food in the two hours before shot time to ensure the PS test is not food influenced. But, as you collect more data and see what kind of food bumps Noel is getting with +1 and/or +2 tests you can take that information in to consideration if he happens to sneak some food when he's not supposed to. Some kittys are super carb sensitive and others like my Jess would get virtually no food bump at all - I learned this by testing and seeing her patterns.
Keep getting those PS tests to make sure it's safe to shoot and try to get as many mid-cycle tests sprinkled around as you can to help paint the picture about what's going on.
