Reducing the dose:
If kitty drops below 40 (long term diabetic) or 50 (newly diagnosed diabetic) reduce the dose by 0.25 unit. If kitty has a history of not holding reductions well or if reductions are close together... sneak the dose down by shaving the dose rather than reducing by a full quarter unit. See additional notes in the next paragraph about drops into the 20s and 30s. Alternatively, at each newly reduced dose... try to make sure kitty maintains numbers in the normal range for seven days before reducing the dose further.

Since 2006 we've encouraged those practicing Tight Regulation to attempt reducing the dose from 0.25u to 0.1u before stopping insulin completely. During a two week OTJ trial, you want to see mostly green numbers (under 100) with only a few random blue numbers between 100 - 120 to help ensure a strong remission.
