Hi Cory!
It looks like Jake is bouncing off of the blue numbers last night. And, it looks like the bounce may be breaking tonight. I'd encourage you to get some additional tests this evening since numbers are dropping from your test at +5.5.
Just an observation -- there's really no way to know for sure where Jake's nadir is. The best way to figure out where the nadir falls is to either do a curve every so often or to get tests at different times. Many cats do not have a nadir at the mid-point of the cycle. (For example, Gabby typically has an early nadir -- usually around +3 or +4. However, there are cycles when her nadir is not at it's typical time.) Cats can have early or late nadirs. Even if your cat usually has a nadir at a given time in the cycle, the nadir can move around.
