Oh, that's just the end of her insulin .. it's the upward part of the 'curve'. Typically the curve of a cycle looks a little higher to start, then dips as the day progresses and often will rise toward the end of the 12 hour cycle. There's an hour by hour walk thru of how the cycle looks in one of the stickies...I'll see if I can find it, or perhaps someone else might have their finger on it easily? If so, please post.
Here it is:

+0 - PreShot number.
+1 - Usually higher than PreShot number because of the last shot wearing off. May see a food spike in this number.
+2 - Often similar to the PreShot number. Onset begins around +2 for most cats. You'll probably see an active cycle if the +2 is the same/similar OR lower than the preshot number. Continue testing!
+3 - Often lower than the PreShot number.
+4 - Lower.
+5 - Lower.
+6 - Nadir/Peak (the lowest number of cycle. NOTE: ECID. Not every cat has a mid-cycle nadir. Adjust the hours on this example to fit your cat.)
+7 - Surf (hang around the nadir number).
+8 - Slight rise.
+9 - Slight rise.
+10 - Rising.
+11 - Rising (one of the quirks of Lantus/Basaglar/Levemir: some cat's blood glucose numbers dip around +10 or +11... not to be confused with nadir).
+12 - PreShot number.
