I know an owner of an acro cat in Surrey, BC who was on insulin for maybe 4 months, got to about 6u and after a few cycles at 6u, plus a change to low carb wet food diet, she shot one dose of 7u, and the cat suddenly stopped needing insulin.
Chuck's been off insulin ever since.
Not all acros are high dose, and some may even be just IAA. The only reason Chuck's owner knows that he was acro was due to their vet suspecting resistance and had Chuck tested.
A low dose, a short time on insulin, a food change.... if he had not been tested, I bet everyone would have said ah, food change; that must have been the problem.
ETA: follow the protocol for your increases, and do not hold longer than the 6 cycles if you are getting nadirs that call for a bit of an increase. When increasing by .5u at higher doses, you don't need to hold the dose longer because the percentage is much smaller at higher doses.
If your dose is 6u and you increase by .5u, what's the percentage? Much lower than a .5u increase to a 3u dose.
You can stick to the .25u and .5u increases until you reach around 10u in dose, then you can move to .5u and 1u increases.
