anemic cat

[Robin Sarafinchan]

Our cat, although he tested postive almost two years ago, has been very healthy until a few weeks ago when he became lethargic and ate less and less.   Blood tests showed his red cell count at 13% so he went in for a blood transfusion on Friday.  He seems a bit better, is eating again, but certainly isn't his old self.  He is also sneezing a bit.   I am wondering what treatment options I can explore and what I can expect from here, what the possible outcomes are.   Thanks very much.
