The feeding schedule is pretty free-form... they get 9-10 cans/day (for four cats) and we mostly just feed them at preshot and whenever they ask. (The advantage/disadvantage of being mostly home all day.) Loosely speaking, I think they get fed at 8 am, 10 am, 4 pm, 6 pm, 8 pm, 10 pm, 12 am, 3 am, and 6 am. So we'll stick with that for the moment but I'll keep the new onset/nadir in mind and adjust if necessary.
I think you recommended 70% of the current dose as a good starting dose? Current dose is 5.5 U, so I was thinking of starting at 4 U and then fast tracking back up to 5ish if it looks like it would be a good idea. Then go more slowly in the ~5 to 5.5 range since that's about his current dose and I don't want to overshoot.
