Okay I'm going to be a big of a nag on this one....Really would like to see you getting a few more spot checks in on him so you have an idea if he is staying flat or if he is actually going down like he should be, those numbers are going to be important shortly when it comes time to adjust his dose.
Normally with Lantus you want to try for about 3-4 tests a day...at very least it would be good to get a pm spot check as a lot of cats run lower at night.
With Autumn I try for her preshots, a +6 and a bed I head to bed at night which works out to about her +3.
