Hi Teresa
Actually, the type of insulin does come into play but still a good idea to post this here.
The "L" insulins do work a bit differently, and the ideal curves with lantus and levemir don't look like what you would see with Prozinc. The goal with the L's is to keep the BG consistent, and you wouldn't see a big smiley shaped curve like you would with Prozinc/PZI. Not to say that kitties on the L's don't get those curves, especially at the beginning, but L curves tend to be flatter once they settle in.
There are times during a prozinc cycle that you would not want food to be interfering with the BG numbers. That would be the two hours or so prior to the AMPS and PMPS tests. That way you know that those two numbers are not influenced by food. As far as the rest of the cycle goes, if Poopy is eating, you just have to try to monitor "when". If he eats at +5 for example, then you have to take that into consideration when you check BG at +6, and expect a number that would be boosted by food. It might make your life harder, but as long as you can account for why a number might be a bit higher, you can manage it.
Is he free fed? Do you use a timed feeder? Is he a grazer or a hoover? Spreading the food out over the cycle is actually a good thing. It makes his BG more consistent and makes it easier for his body to regulate the rises and drops due to food and insulin, especially if his pancreas is helping out like you want it to. The prozinc is going to have the most influence on his BG in about a 4-5 hour window from +2 to +6 or +7. After that it starts wearing off until it is used up, just in time for his next shot.
