Jan update II -

She doesn't have any of the nasty stuff, FIV or Leukemia...

She is however showing a yellowish color in her blood serum which means that fatty liver disease is a concern right now so the action of force-feeding her is the correct one. Fortunately her liver enzymes look good. This is probably a secondary symptom of the original problem of having a fever and lack of appetite.

The vet is also prescribing an appetite stimulant pill so now we get to pill her, medicate her with the liguid antibiotics, and force feed her.

We could leave her at the Vets to be force-fed, but I think she'll be happier at home and the two of us can manage to do this.
