I've been on this board for over 7 years. I've seen the other feline diabetes message boards crop up and the one that follows Hodgkins' recommendations is hugely problematic. FWIW, the Hodgkins method of tight regulation (i.e, not feeding your cat high carb when numbers are low) has literally killed cats. No one wants to see your cat die from hypoglycemia. I would forget anything and everything you've learned from Hodgkins. Her dosing recommendations were developed based on the original formulation of Prozinc and therefore cannot be generalized to a long-acting, depot type of insulin. It's apples and oranges.
Cats are notorious for hiding how they are feeling whether it's illness, pain, or low blood glucose. I would not trust observation over the readings on a glucometer. Gabby's numbers would drop into the 20s or 30s and she would look fine. The good thing was I would test diligently and she never spent any length of time in dangerously low numbers. We do not know how long it takes for a cat to be in those kind of low numbers for organ damage to occur. Once you start seeing symptoms of hypoglycemia, it could be well beyond a margin of safety and you are looking at a very expensive stay at the emergency vet to get numbers back into a safe range. Your glucometer is your cat's best friend and the only way to keep your kitty safe. It's your choice how much you test but with the kind of numbers you're seeing, basing your cat's BG level on your observation, IMHO, is playing with fire.
All of that said, at the very least, I would skip a day or two of shots. It may empty the depot a bit and give you a chance to evaluate whether insulin is even needed.
