Hello! I agree that you should be testing for ketones since you are seeing those higher numbers. As far as dose advice, I am not going to tell you what to do, only your choices. You can either keep the dose unchanged and continue to test, and this really need to be at least 3-4 a day. Having mid cycle test is really crucial in being able to know what dose to give. Just having the pre shot numbers tells you only if its safe to shoot. You are getting other test done that I can see, but please try to get a +6 or +7 in both the am and pm cycles. Many of us here that work and cant test during the day, will set an alarm to get a +6 or 7 after pmps. Also, if you work, on your days off you should do mini curves, which means test every 2-3 hours from amps-pmps. I have someone who test for me during the day, and I am fortunate for that, but before that, I would get amps/pmps and then a pmps+2, or 3, and then sometimes at +6. I caught some low numbers that way. If you cant do that, then you could drop the dose down to 1u and see what happens, but be prepared to increase back up if there is no improvement. Im only telling you your choices here, and he may be dropping during the night and bouncing way up by morning, or maybe he isnt and needs more insulin. Without more data, its impossible to know. I hope Mel or someone else can give you advice soon, I just wanted to give my opinion, for what its worth. I hope you kitty is doing ok otherwise.
