I would tend to avoid MC for a preshot meal if she's in a range where you are comfy shooting. The 5/4 or yesterday AM shot made sense for MC, at least until you have more data on shooting green. The Lantus doesn't onset for a couple hours after the shot, and numbers will keep going up until then. Feeding higher carb at PS will make the BG go even higher up to onset. Use the +2 (or thereabouts) and whether it's a sizeable drop from preshot to decide if you want to give MC then. Or if you aren't certain and are away at work, MC in the feeder might be appropriate. As Kitty becomes more regulated, you may find that what you need to feed when may need to be adjusted.
