This sounds like our Tuxie.
The one thing I would say is that if the prednisone doesn't work, they have to consider trying Depomedrol. They are both steroids, but they DO have a slightly different mechanism of action. Tuxie never had a prednisone injection, but we gave it to him orally. Now maybe that makes a difference. And it worked at first, and his RBC went up. But then he stopped responding to it. Our vet consulted with feline blood specialists, and decided to try the Depo, which is the standard of care when dealing with Feline Hemolytic Anemia. Now - that wasn't Tuxedo's diagnosis, but he was a medical mystery (still is). But the treatment for the FHA worked.
I don't know how much you've learned about anemia yet, would you like some quick basics?
