Calle passed her first blood test. The second one was today, with chemo scheduled for tomorrow.
The hospital called me back today. Turns out her red blood cell count was about half of the lowest acceptable level, so we canceled the appointment. I've got antibiotics to give her, and next week, she'll go back in for another blood test. If that's okay, we can proceed with chemo.
Naturally, she doesn't care. Looks like the same old Calle, except with a bit less fur (the stomach fur is starting to grow back; the neck and leg won't stay regrown until we're done because they need the leg for chemo and the neck for blood work).
Well, she probably won't like 14 doses of antibiotics. Neither will I. I did get a useful tip, though. We'll see how it works out.
