Step 3.
After 1-2 weeks at a given dose, you or your vet should perform a serial blood glucose curve (blood glucose tests every 2 hours, starting at shot time and continuing until the next shot). Follow the cat's normal feeding schedule during the curve. The curve should be evaluated by someone experienced at interpreting feline blood glucose curves, in order to check for signs of rebound and other possible problems. If no rebound is present, follow these guidelines for dose adjustment (smaller adjustments may be appropriate for cats on PZI or Lantus):
If the lowest point of the curve is above 150 mg/dl (8.3 mmol/L), increase the dose by 0.5 unit.
