Are you able to dose in 0.25u amounts? With SLGS, the doses are raised and lowered in 9ncrements of 0.25u. You have to eyeball the dose since the syringes are marked in 0.5u amounts.
Not a blue preshot but looks like his nadir is at +6
With Lantus, some cats do what is called a "double-dip". They go down till their nadir and then up again and then dip again at the end of the cycle. The second dip is shallower than the nadir.His number was high a few hours after his +6 snack but settled back below 300 at his PMPS. So weird.
