I don't really know, lol. I am kind of winging it - if I got a 125 at a +12 I probably wouldn't shoot, but if was a +36 I probably would. Definitely shooting above maybe 135-ish though. At one point Steve & Jock tentatively said maybe 110 as a no shoot, and I was kind of going with that on my human meter, thinking the human meter ran low, but it made me really nervous, which is why I switched back to my cat meter. On it, I am definitely not shooting anything non-diabetic, so 120 or slightly higher is probably my absolute cut-off. If I were using the human meter I might go a little lower than that.
All that, however, is for a cat who has spent a few months dancing in the low-100s and then went higher, so I am clear with him that his pancreas just isn't ready to go it alone. With cats where that is more of an unknown, I would probably set some time limit on things - like I wouldn't shoot a 130 or 140 if I just saw it, I would maybe try feeding and testing a couple hours later. Maybe set some limit (4 hrs? I have no idea really) and if the #s haven't dropped by then, then go ahead and shoot. With him, I'm not waiting at this point to see what happens in a few hours, since he is a hoverer & drifter upwards on the whole. But on the other hand I can't afford to test every few hours, so I am mostly sticking with tests every 12 hrs, or if he keeps being too low in 12, I'll probably go with something like 16s.
Not sure if any of that helps.

If we could entice Steve & Jock to stop by, he has some experience I think with this kind of situation, and might have tips. I'm sure there are others too who would have insight. Since ECID and so far I haven't gotten Bix to show improvement from this point on, I'm not sure how much use my thoughts on the subject are.
Did I already post this TT thread on the subject?
