Hi Adam,
I don't think your current vet knows very much about feline diabetes at all.
It is great you are home testing and asking lots of questions trying to find out what is best for Mogee.
Food is key in getting a cat regulated. You need to change to a low carb wet food early on in the process, not waiting until later.
When you do change over to a low carb wet diet, you need to be testing regularly as the blood glucose will come down and you need to be able to keep your kitty safe.
You are not micro managing or stressing your cat by testing the number of times you are doing it each day.
Your vet wants you to blindly increase the dose without seeing what it does to the blood glucose. That is risking a hypo.
If I were you I would continue testing as you do. I would always get a preshot to ensure it is safe to shoot. And at least another one around the nadir to see how effective the insulin is.
Wanting to increase the dose of insulin from 2 to 4 units is DOUBLING THE DOSE!!
We recommend increasing by only 0.25 units at a time and waiting at least 3 days ...6 cycles....to see how the dose works. Insulin is a hormone and does not work like an antibiotic for example. It takes time for it to adjust the glucose in the body. If you race through the doses you are not doing what is best for Mogee.
Please do not go up to 4 units tomorrow as you have written in the SS.
Do you have honey and high carb food at home in case of a hypo? Here is a link to hypos. I would print it off and put on your frig in case it is ever needed. That is what a lot of us do.

Personally I would be looking for a new vet.
Mogee is beautiful.Keep asking lots of questions, we love to help
