Could you update your SS to show the rest of the data? We don't like to make suggestions on doses without seeing the data. I'd still try going back to maybe 1.25U if you can. Kitties are very sensitive to small increases as you can see by today's cycle. One method is to try with an old syringe. Put in 1.5U of colored liquid of some kind, point the syringe up, then rotate to squeeze out drops. Count the number of drops down to 1.5U then cut that in half to get your 1.25U dose. It may take a bit of practice. I use a magnifying glass too and can see if the insulin is to the top or the bottom of the marking.
