I guess I need a better understanding of going low. I thought, as long as not super low (hypoglycemic) ranges, it was a good thing to show low numbers during the day. Could you, please explain the concept behind low and feeding at that time. Is it more important to try to keep a relatively flat line (at higher values) than hit the low numbers intermittently? Is that even a sensical question?!It's easier on what we hope is a healing pancreas to have multiple small meals a day. Human diabetics do the same. Some people get automated feeders to do this when they are away, or at night when asleep. Some people have grazers, so it's not as much of an issue with them. But if kitty is a hoover, or another kitty in the house eats all food right away, that doesn't leave any food for the diabetic cat.
The best times to feed those meals is in the first half of the cycle or before nadir, when the insulin effect is the strongest. After that, carbs can cause the insulin to lose duration, meaning not last as long, and result in higher preshots. A little snack just before nadir time might help if you are away and she is going low.
Do I reduce now? Or wait for the next under 90? So, giving her a midday snack is not necessary every day? Only if she’s running low?What you want to do is provide food when she is in low ranges, especially in hypo ranges or in danger of going there, especially if you are not around during the day or asleep at night. Food is what keeps kitty safe. So you don't want to necessarily keep flat higher numbers, but you can allow her to get lower, but not dangerously low.
I took a look at your spreadsheet, and I see she got down to 79 and 82 a couple days ago on this 0.5 units dose. When following SLGS, you reduce immediately by 0.25 units whenever they go under 90. So you should have reduced to 0.25 units that night.
