When you get a number like that, wait to feed her to test her again in 20 minutes. Yea, I know she'll go nuts wanting her food and all but that way you can be sure she's rising to have a better idea of what to shoot. :smile:
I think I'd go with the .5u, and probably go skinny just to be safe, if not a little less. It's a pretty low AMPS (given the 20% variable, you could almost say it's a normal cats' BG).
Let's see what those with more experience have to share. They may advise to go lower. :smile:
