You don't want to wait that long before you do another curve. We recommend a curve or at least some more random tests to fill in the SS, and then reevaluate the dose in 1 week. A month is way to long to keep your cat on the same dose, IMHO.
What happened on 9/5, 9/7, 9/14? You should have a row for every day. Even if you are not able to get tests, Pabay got insulin, and we really need to see that information to help you the best.
