Thanks, everyone
I called last night before I went to bed, and they said she hadn't vomited or had diarrhea, and that she's doing great so far.
They told me I can call after 9am to check on her... so I'm waiting another 10 minutes.
I really hope we can pick her up this evening. It's hard seeing my spunky little girl so sick. She only weighs 2lbs, 12 ounces.
This is our first "emergency vet" visit we've ever had to do. Hopefully it will be the last for a while!
