Good news!! Kuqi's blood glucose readings are definitely looking better.
Since Kuqi has started to drop lower in the middle of the cycle, you probably do want to consider how you could get a few BG tests in during the night cycle.
Many cats are more active at night, use more energy, thus use up more blood glucose and drop lower. Sometimes much lower.
Some people adjust the insulin test, feed, shot routine so they can get a test or 2 in at night.
For example.
Say your current routine starts with the AM cycle at 8 am, and then the night time cycle is at 8 pm. If you head off to sleep at 11 pm, that would allow you to get a +2 and/or a +3 test in during the night cycle.
You might adjust your routine and times for the 12 hour dosing cycles.
Maybe get up at 7am to test for the AM cycle and then your PM cycle is at 7 PM. Now, you have the option to test at +2, +3, +4.
Some people set an alarm to wake themselves up and take a blood glucose (BG) test.
Options for you to consider. You do what fits your schedule and life.
p.s. Did you find a good low carb food that Kuqi likes to eat?
