My cat has been on Vetsulin for 13 days now 91U twice a day. I've been testing twice a day (AM/PM) as close to 12 hours as possible and her numbers range from 255 to 350 on Average (low of 209 and high of 379). I working on getting a curve, so gave her shot and have been testing every 2 hours so far. It's shot +3 hours and she's at 77. (I'm using AlphaTrak2). That seems really low. I gave her a Purely FF treat (no carbs) as a reward. My question: Is that number too low? At what point should I worry? Is giving her a zero carb food okay to try and get the number up just a little? Or is that number just fine and it's simply not one I've seen before. Any advice appreciated!!
