BigGirl was right, and I was wrong. All day she (since seminary at 5:30 this morning!) she has felt like Phantom would have the kittens today. I maintained that she had another week.
We have kittens!
So far, a little yellow, and a black (or possibly dark tortoiseshell like mom), who has already been "dibs-ed" by LargeBoy, and named Loki. I don't know if she will have more, since this is her first litter.
