Hi again, Rose. I know I posted in PZI before I left for the Dr this morning but I thought I would say it here now too.
I don't think that 1u was a bad choice at all but if I were you I would test a few times today and keep an eye on those numbers. It might well be that the 1U is still too high so I would religiously keep that SS up and depending on how Fluff responds I might consider a slightly lower dose before any possible increase.
My reason for saying that is the reason I posted last night after your crisis was over. It is entirely possible that since it looks like you completely removed the dry food that Fluff needs less insulin.
Again, you did an amazing job yesterday under huge stress!
