I called the vet today at 07:30 and got an appointment at 11:5 for tomorrow, then pushed it back to 11:30 because Andy has an important meeting starting at 10:00. The receptionist called back a few minutes later; the vet is coming in early and she offered us a 10:00 time slot for today. This is good because Gail gets seen sooner and Andy can work from home and not worry about bailing on his meeting.
I have no idea if Gail will still be getting her teeth cleaned on Thursday. I imagine a lot will depend upon how much she weighs and what can be done to get her eating in the next day and three-quarters. Since force-feeding most emphatically didn't work we have a new feeding strategy pending the emergency appointment: baby food.
