You did a great job last night.
What we can definitely tell you is that 1 unit is too much.
And if you've got the diet change to low carb going, that may have done the trick in getting his glucose lower.
Also, cats who have gone very low in insulin may now be more sensitive to it; you'll want to be very cautious about any further dosing.
We use a really handy grid to record our daily glucose tests - it color codes the values to give you a clue about how the cat is doing. Instructions are
here.
Understanding the spreadsheet/grid:
The colored headings at the top are the ranges of glucose values. They are color-coded to clue you in as to meaning.
Each day is 1 row. Each column stores different data for the day.
From left to right, you enter
the
Date in the first column
the
AMPS (morning pre-shot test) in the 2nd column
the
Units given (turquoise column)
Then, there are 11 columns labeled +1 through +11
If you test at +5 (5 hours after the shot), you enter the test number in the +5 column
If you test at +7 (7 hours after the shot), you enter the test number in the +7 column
and so on.
Halfway across the page is the column for
PMPS (evening pre-shot)
To the right is another turquoise column for
Units given at the evening shot.
There is second set of columns labeled +1 through +11
If you snag a before bed test at +3, you enter the test number in the +3 column.
We separate day and night numbers like that because many cats go lower at night.
It is merely a grid for storing the info; no math required.
