We include those so people can follow the history.
We determine the Lantus dose primarily based on how low it takes your kitty, not the preshots. Those lows are typically somewhere in the middle of the cycle, hence the importance of getting tests then. The before bed test is a really good one to get, as many kitties go lower at night and our dosing methods need to find those lows. Without mid cycle tests, we don’t know if Simba is diving really low during the middle of the cycle, then bouncing back up. Or if the dose is just not high enough. My Neko earned her first reduction, going under 50, starting the cycle at 430, diving down, then bouncing back up by end of day.
As Bron suggested, 1.0 units is too much insulin and here we find it easier to figure out a good dose if you shoot the same amount in the AM and PM. Otherwise you are constantly disrupting the depot.
SLGS really does work, but you have to follow the guidelines to find a safe dose that gives you good numbers. Patience is key, give the insulin time to work. Rushing increases, as you have done without testing to know what is happening, could push Simba up to too high a dose, risking a hypo. Simba will get there. Feline diabetes is a marathon, not a sprint.
