Question about low glucose readings

[KiKi's Mommy]

My cat KiKi has been reading low on my home glucose meter for a couple weeks. She originally had unregulated numbers (and went into DKA and was in hospital for two days) but after her follow up ultrasound, her clostridium flare up is back to normal (with the help of metronidazole) My vet did a fructosamine test and her average was 294. When I checked her glucose the other day after eating but before her shot, she was 79. I called the vet and asked if I should decrease her insulin (she is currently on 4 units twice daily), she said no. I tested her again tonight after eating but before pm shot and she was 79. I didn't want to give her 4 units so I gave her 3.5. Am I doing something wrong?

I forgot to add that she's been on a low carb diet for a couple months. Finally!!!

Here's your previous post for some people to get the backstory: Newbie

It's great that you've got her on a low carb diet now. I suspect that may mean 4 units is now too much insulin. Moving to a low carb diet from a higher one can make a big difference in the amount of insulin needed. What was her old food?

Could you tell me what type of insulin you are using? 79 was definitely too low to shoot 4 units at this point in time, so good instincts. Can you tell me what brand of glucose meter (we also call it BG for blood glucose) you are using?

We'll be able to give you some more detailed help if we can can get answers to the above questions plus able to see some more of the blood sugar data you have been collecting, even if only for the last couple weeks. You'll notice that most of us have spreadsheets in our signature where we document the blood sugars. They are incredibly useful tools to help give us a picture of what is happening. Details on how to do that are in this post. New? How You Can Help Us Help You! Let us know if you need help setting it up.
