Hi Missy! and Welcome! I'm so sorry that all of this is causing you stress. It's difficult at the beginning when there is so much to learn, but it does get easier with time. And we are all here to help and walk with you through this journey. You are not alone!
Prozinc does have a bit of carry over in many cats, so it isn't as volatile as Novolin. There is actually slightly less chance of hypo as long as your kitty is on low carb food and you are monitoring carefully at home. Although it's always possible with any insulin. Prozinc still has a smile shaped curve, but not quite as steep on the drop and rise as Novolin. In some cats it wears off around +10 so it doesn't have as much carry over, in other cats it can last a bit longer which makes the curve a little more gentle. So for cats that do well with it, and are properly dosed, Prozinc is somewhere between Novolin and Lantus in its dosing and impact.
Starting dose is comparable to what you are on right now. So if you are at 1.5u, you would switch over at 1.5u but be sure to do it during a few cycles when you can get mid-cycle tests to be sure she's transitioning okay.
Cats respond to different insulin types in different ways. My cat has done great on Prozinc, but mediocre on Lantus and awful on Levemir. It just takes some trial and error to find the right insulin for your cat sometimes. If your vet is amenable to making changes, you might also consider Lantus. Many cats do really well on it, and the dosing "rules" are quite strict so there is a little less art/guess work than there is on Prozinc. For some people that helps to lower their anxiety about all of this. Personally I found it a bit too inflexible, but I have control issues
If you do decide to try Prozinc, we are here to help!
