A. Was your kitty wormed. Anemia can also be caused by a severe intestinal parasite load. But I am sure your veterinarian covered that. Here is some information: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748294/
Unfortunately FIP is a lethal disease, however the signs are unspecific and many other diseases can look like FIP. I hope the Doxycycline has an effect which would point towards another cause of your kitty's illness.
