Hi Jen and Tink!
I haven't posted on Tink's condo, but wanted to extend a belated welcome to LL. :smile:
Like Julie mentioned, it looks to me like Tink's probably headed into a bounce. Since Lantus is a gentler insulin than ProZinc, bouncy kitties will often head up rather than down after a shot if they're in a bounce cycle. Take a look at Eddie's SS...he does this all the time. :roll: In fact he's doing it this morning.
I know when we were on ProZinc, I didn't see a lot of kitties having high flat cycles, and it took me a while to understand what was going on. There's bouncy pre-shots, that are big spikes at the beginning and ends of a cycle, and then there are the flat bounce cycles. Those flat cycles where the numbers go up from pre-shot, or where they don't really go down much are often bounce cycles. Those bounce cycles can stick around for up to 72 hours after the "event" that generated the bounce. Over time, the length of time a bounce lasts generally decreases, and they don't bounce as high....and eventually, many kitties stop bouncing all together. It's possible that Tink is still bouncing off the blues on 8/11, or he may have gone lower last night. He had a fairly sizeable dip between PMPS and +3 last night that might have led to some lower numbers later in the cycle.
Another difference with Lantus is that a cat's patterns can stretch over several cycles. For example, a cat might have a string of green numbers one cycle, bounce for two cycles, start to head back down on cycle number four, and then have another string of greens on cycle 6. Then, wash, rinse, and repeat, until they decide to change their pattern up on you, as cats do. ;-)
If no one has mentioned it yet, one good habit to get into is getting a +2 test. For many cats, if the +2 is significantly higher than the pre-shot, your kitty may be headed into a bounce cycle. If the +2 is about the same as the pre-shot, that's pretty typical, and a kitty will often have a "normal" curved Lantus cycle. If the +2 test is significantly lower than your PS, get ready for a cycle that might keep you on your toes. For Eddie, getting a +2 test has been hugely helpful in starting to be able to better predict what he's got planned for a cycle. Since I work full time, if Eddie's +2 is lower before I leave for work, I will leave extra food in an auto feeder in case he decides to "get busy." I actually moved Eddie's shot time as early as we could to get those early cycle tests in, as they are almost as informative as the nadir test.
Hopefully Tink works his way back down soon and gives you a better idea what he can do at 1.75u so you can decide whether you need to increase or hold. Have a good day!
