Hi and welcome Denice and Sapphire. I'm glad you are committed to learning more about how to treat Sapphire's diabetes and you will find the information and support you need here on the board. She is a beautiful cat and I know you want her to be healthy and feel well.
The Fancy Feast classic pates are low carb and a good diet for sugar cats. There is an excellent website about feline nutrition:
www.catinfo.org that you may want to visit. The DVM who runs the website has also created a wonderful food chart broken down into components (protein, fat, carbs, etc.) of many brands that might be helpful to you.
Many of our U.S. members buy Lantus from Marks Marine Pharmacy in Canada for lower costs. We can tell you more about that if you are interested.
You mentioned glucose testing supplies, Hooray for you! You have ticked off the three basic components of effective feline diabetic care.
Please create your signature so that Sapphire's info is available with your posts. That's the gray text under all our posts. Here's a link to the signature and profile instructions:

Another thing that will help us help you now that you've started BG testing at home is to set up a spreadsheet like the one we use here. We can all see it and look at it before offering advice:

Please post questions and concerns on the Main
Health forum and you also should visit the
Vetsulin forum for more information about that insulin.
Best wishes going forward.
