Remember to test at +2 Patty. That can tell you the direction the BG is headed.
Copied this from Chris & China (GA) ages ago.
"The +2 is like an "early warning" for most cats!
If the +2 is about the same as the PS, it's usually a pretty normal cycle...dropping down to nadir and then rising back up again.
If the +2 is higher than the PS, that usually signals a bounce, and those are the cycles when you can usually take a break from testing.
If the +2 is lower than the PS, that's your "Early warning" that kitty might be going much lower later in the cycle so it's important to plan on getting another test or two (or 6) in.
It doesn’t work every time or with every cat. But it does hold true most of the time, so keep this in mind for next time."
