In parallel to Marje fixing your SS to capture the changes for using Human meter from Pet meter going forward, it would be good if you can try and stay on a dose consistently for several cycles, since the dose hopping can cause some disturbances and ability for the depot to build. I don’t think a doing a rebound check and going down to 1u will be helpful, although it is difficult to see how dose increases occurred from January until more recently.
I think I would be inclined to stick with 4.5u consistently for the next several days, and continue to test preshots and get those random tests in at least once in each cycle. Let’s see after a few days on the same dose what’s going on. You are getting some nadirs in the yellows with pet meter, but I’d like to see how Egon does on the same dose, over the course of the next several days after allowing the depot to build.
Any other cats in the house who are fed different food not low carb? And if yes, any chance Egon is getting into it?
