Hi and welcome Lisa and Twigs. As Sarah&Soph told you, many members at least start out with the ReliOn Prime meter and strips from Walmart, because of affordability and availability. Pet meters are a relatively new product and are much more expensive. The important thing is to be testing and being able to see the trends and patterns of insulin action throughout the 12 hour cycle between shots.
Since you are using Vetsulin, please visit that insulin support group forum
HERE and read the Beginner's Guide to Vetsulin. Unfortunately many vets recommend a higher starting dose than needed. It's easier on the cat if you need to increase the dose by small increments than give them a whopping big doses at first and have to work down. When kitties get those big doses and BG drops drastically in response, the liver releases stored sugars and hormones trying to balance out. Then you have very high to very low cycles that you don't want kitty dealing with. In the Beginner's Guide it is recommended to start with one unit 2X a day.
Please take a little time and create a signature and set up the spreadsheet so that we can see Twigs' information when you post:
1. Setting up your signature (light grey text under a post). Here's how:
click on your name in the upper right corner of this page
click on "signature" in the menu that drops down
type the following in the box that opens: kitty's name/age/date of diabetes diagnosis/insulin you're using and dosage amount /glucose meter you're using/what (s)he eats/any other meds or health issues (s)he has. You can add your name, and a geographic location (sometimes the time zone matters) Be sure to SAVE when you are finished.
2. Another thing that will help us help you when you get started BG testing at home is to set up a spreadsheet like the one we use here. You will see how the trends and patterns emerge, and members can review his/her progress before offering suggestions or advice:

If you have any problems setting up the spreadsheet, let us know, there are members who can help or set it up for you.
We want to help you navigate the path of learning to provide effective diabetic treatment for Twigs and not feel inundated or overwhelmed. We will help with proper diet suggestions and information, as well as how to test the blood sugar so you know exactly how the Vetsulin is affecting her. Very best wishes going forward
