Hello and welcome. I moved your post to Feline Health where we ask new people to post first, plus this question is relevant to more than just Lantus users.
At FDMB, we believe in three things to help our diabetics. The first is a good insulin for cats. Since you posted on the Lantus forum, can you confirm that is what you are using?
Second is home testing the blood sugars and it sounds like you are doing that. What type of meter are you using? Some read differently, pet vs. human vs. Libre, so it's good for us to have that information.
Third thing that's important is to feed low carb wet food (or raw). For die hard kibble heads, there are a couple of low carb dry food options, but Orijen is not one of them. Low carb to us means 10% or less carbs. The Orijen is about 18% carbs on an as fed basis, so we'd consider that high carb foods.
To answer my questions above, which will be common questions, you can put the answers in your signature. This post tells you how, and what other information can help us.
New Here? How to Help Us Help You
You will find that if you change Moji's diet from dry high carb food to wet low carb food, her insulin needs will change quickly lower. That 99 you got today is telling you that. If you could fill in the signature, and help us get a better picture of her blood sugars by filling in a spreadsheet, we'll be happy to help you with a strategy to get her more regulated. By the way "sugars all over the place" is the most common phrase used by new people. It's annoying but very common for new cats to have numbers bounce all over the place. She'll get over it eventually.
