Hi Brandy,
Welcome to Lantus! I wanted to give you a bump, and what limited advice I have. Props to you for home testing and catching the hypo!
I'm posting your condo from the main board concerning the hypo so everyone is able to quickly reference the situation if need be.

Personally I see no harm in grabbing a mini curve today (3,6,9); especially since lantus is long acting and it looks like he got a shot last night and this morning, and he got some dry food during the hypo incident yesterday (please let me know if i'm miss-quoting). It may not be a curve in term of a "this is my cat on a normal day" curve, but it will help you out to get some light posts, especially after the hypo.
