It is normal for a cat to be bouncy as they settle into a dose. Usually the bouncing settles down, but some cats bounce all the way to remission. Bouncing can be caused by a cat getting into numbers they are not used to and then their body panics and sends them back into higher numbers until they get used to the lower (more normal) numbers, or by dropping fast.
It looks like Angel is bouncing from getting into those nice blues and then the insulin is bringing her back down to normal numbers. Since you are following SLGS, and she went below 90, you reduce by 0.25 units. The new dose will be 1.75 units. She may go up and down in dose before you get her into good numbers. She is doing really well right now. Since you skipped the shot (that is a good call since you are new to Lantus and green numbers), she may be high this evening.
