Twinmommy,
She actually looks pretty good, except for the emaciation.
So we're playing it by ear, keeping her isolated when we're not home, and letting her out when we're here. Darla is dealing well with it, the occasional hiss, but nothing bad. And Coco kind of responds as if "well, look I got some problems, and I just can't deal with you right now, so um, leave me alone."
Anyway, time will tell with this little munchkin. I'll keep everyone posted. I have good feelings about how she's doing, however.
Talk soon.
