I've taken the curve results, and added the cycles and the + hour times that we use. + hours are counted after the dose of insulin is given.
LK curve test 2 - 1 April 20
AMPS 1) 08:45 - 32.1 mmol/l (or 576.2 mg/dl)
08:50 Breakfast + 3 units injection
+2 2) 10:45 - 27.6 mmol/l (or 496.8 mg/dl)
+4 3) 12:45 - 20.9 mmol/l (or 376.2 mg/dl)
+6 4) 14:45 - 26.9 mmol/l (or 484.2 mg/dl)
+8 5) 16:45 - 26.3 mmol/l (or 473.4 mg/dl)
+10 6) 18:45 - 34.4 mmol/l (or 619.2 mg/dl)
PMPS (+12) 7) 20:45 -
dinner at 20:50 + 3 units jab
A couple of observations.
1. With Caninsulin, it's recommended that you wait about 20 minutes after feeding, to give the shot of insulin. That is so the food has time to digest and get into the bloodstream to counteract the faster onset of this insulin. That is not an issue for LK right now, but it could be one later, if the higher and higher doses drop his BG levels a lot.
2. Doesn't look to me like the insulin is lasting much past 6 hours. But that quick BG rise at +6 could partially be from the dry food.
3. Dry food is almost all high carb. Grain free does not mean low carb. Ingredients such as peas, potatoes, tapioca, and other starch sources are substituted for the grains.
4. Feeding after the insulin has been used up, has "pooped out", simply leads to the BG levels rising in the last half of the cycle. You might think about feeding in the first half of the insulin cycle only.
5. If those are the tiny 85gram tins of food, that doesn't sound like enough.
6. If you take away the dry food, Dr LK's BG levels are likely to drop by 5.5 mmol/L (100 mg/dL) basis points or more.

The RVC (Royal Veterinary College) in London, did a study a few years ago, a diabetes remission clinic. They found that Prozinc works better in cats. Of course, if your cat is getting good blood glucose control, the study did say there was no reason to switch from Caninsulin.
Here is a link to the study.
