Hey. I see your curve filling in on the SS, so that's great.
A couple "forum etiquette" items:
In the Lantus forum, each cat should start 1 new topic each day (we call it the "condo"), with a subject line like this: "8/22 Heathy - AMPS... etc."
As you get more data, or have new questions, during the day, go back to the first message and "edit" the subject line so that it updates the displayed subject in the main Forum list
Seeing numbers in the 200's and low 300's in the first few days on Lantus seems to be very normal from what I've seen. Having higher readings in the middle of the cycle sometimes is also very normal early on. Until Heathy is "regulated" consistanly below 200, you may not have a normal curve at all. One problem this causes is that you cannot just test at +6 and be confident that you have seen the lowest number in the cycle.
Do I ready your SS right that you are testing and shooting AFTER feeding? In general, the recommendation is to get the test in before feeding to make sure that you are getting a clean reading not affected by the food. The shot should also happen either right before feeding, or frequently during feeding while your cat is distracted. Lantus usually takes an hour or 2 to kick in, so if you delay shooting until after the meal, the food gets to the bloodstream before the insulin.
Otherwise, how is Heathy doing?
