Have you tried posting over in the Lantus & Levemir forum? It's designated specifically for cats using the insulins Lantus/Levemir. There are a lot of wonderfully knowledgeable individuals there that can help guide you through your feline diabetes experience. There's also a plethora of sticky notes giving you valuable information located at the top of the L&L forum page.
Before you post read the posting guidelines, as it helps others to help you more efficiently. When posting there things are kinda particular but, there is a reason behind all the madness. The forum flows more smoothly when peeps post in a certain "format" so to speak. I really encourage you to give it a try.
And as jt mentioned, the spreadsheet is one of the most valuable tools we utilize. It helps to visually track changes in BG patterns and allows others to see the big picture, to better advise you.
