CW went to the vet today and got a B12 shot and she and two of her negative buddies were "typed" to confirm they are compatible for transfusion (I have at least two good donor cats). Since CW is eating great (without any appetite stimulants) and not in any respiratory distress and her overall attitude and appearance is very positive, the vet said we could do the transfusion on Friday once with confirm the blood typing compatibiliy -- although it would be very rare, if the cats were not compatible, we might make things worse. My vet thinks the drop in RBC has been chronic and very gradual and may not dropping as quickly as sometimes since there have been no other symptoms....so a wait of 2 days was ok.
I am willing to try the epogen and prednisolone provided giving them is not a struggle and stressful to CW. I know this is not a cure, but since her qualitiy of life is still good, I sort of feel that I owe it to her to try and maintain that. I will keep folks posted. I am going to look into the supplement you suggested, too. Thanks, Tracy
