Unfortunately, her liver is swollen, and pressing up against her stomach, and she's not eating. Of course, cats don't generally eat very well at the animal hospital, but still, it worries me. Tomorrow, they're going to do some surgery and try to biopsy her liver. I've been forewarned that there are always dangers when there's surgery, but I think it's a risk that we have to take, and I'm confident that she'll pull through just fine.
Thank you all again for your kind thoughts and prayers for her, and for us. They've helped tremendously.
