Things can change a lot in an hour
The problem with feeding at +11 is now when it's shot time, we won't know if Boots would have continued to drop or if the only reason she's up higher is the food
Robin, it's really important to try to get some tests in during that PM cycle, even if you can just grab a test on your way to bed at night. Most cats go lower at night and it's important to know if that's going on
Since she's new to greens, I wouldn't be surprised if she goes really high again due to "bouncing"...any time a cat goes into low numbers, lower than they're USED to being, or drops a lot of points quickly, their liver can react and release stored sugars and hormones to bring them back up fast..they "bounce"
It's important to not increase during a bounce too since when they start to "clear the bounce", they can clear it fast and if you happened to increase at the same time, you can cause problems.
