Hi Katie and welcome to you and Ovie,
Generally we Test, Feed, and Shoot more or less simultaneously (in that order). There is no need to wait 30 minutes after testing to shoot. The 69 you got this morning probably indicates that Ovie's dose is too high. We have two protocols in the Lantus/Levemir Forum and you at some point will have to make a decision as to which one you want to follow: TR (Tight Regulation) and SLGS (Start Low Go Slow). Both are described in the "Stickies" (informational posts at the top of the page). Whichever one you decide on, a Spreadsheet will help others to help you. There are instructions for setting up a Google Spreadsheet in the Tech Forum:
http://www.felinediabetes.com/FDMB/threads/fdmb-spreadsheet-instructions.130337/ Ask if you need help setting one up. You will need a Google account to begin.
There are "cut-off" numbers for each of the protocols (i.e., numbers that are too low to shoot). I don't remember them offhand, but please read the Stickies.
I'm not familiar with the Prodigy meter. Many people here have found the Walmart Relion meters (either the Confirm or the Micro) to be a good choice. The strips are not expensive and the blood sample is very small--an important consideration.
Feline Diabetes is an adventure. The people here will help you get on the right path! Welcome!
