Your AMPS numbers are missing on your SS for 11/4, 11/5, and 11/7 (today).
A bounce can occur in one of two ways. A cat can drop into lower than usual numbers (which could be a green, a blue, or even a yellow) or the cat drops quickly into a lower range of numbers. When this happens the liver "panics" and releases a stored form of glucose along with counterregulatory hormones. These cause the BG level to spike upward. This is the body's way of protecting itself from what it assumes is a dangerous situation. It's a normal process.
It doesn't mean that Bailey was in a dangerous number zone. It may mean that your cat isn't used to being in blue numbers.
