I just called the hospital. The vet won't be in until 9:00 (so I'll be calling during my prep!), but the technician said she appears to be resting comfortably, still on her IV and antibiotics.
I told the tech, "I'm just a worried Mama!" He just laughed and said, "That's normal!"
I suppose it is.
Everyone, please keep your fingers (and paws!) crossed that my Millie-girl can come home today.
