Cat just diagnosed with Feline Leukemia - info/resources requested

We took our 11/2 year-old male, sweetheart of a cat in to the vet because
he was lethargic, and the vet diagnosed auto-immune anemia. Further testing
showed that he had an 11% red blood cell volume (normal is 35-50%) and is
positive for Feline Leukemia.

Oh boy...

We've decided to give him the best chance he can have to get back on his
feet and keep him with us for as long as we can. So, he had a blood
transfusion last night and for the next few weeks he's been prescribed
steroids and antibiotics, as well as Felovite vitamins. In a week he'll get
another blood test and we'll see how he's doing.

We CAN'T loose this cat, period.

So, I would appreciate it if you folks could point me to some info/resources
on getting him past this anemia and making his life with leukemia as healthy
and long a one as we possibly can. There's a ton of stuff out there (I know,
I've been digging through it) but it's hard to tell what info is current and
reliable. Has anyone had any luck with supplements/medication that we can
give him to help him fight the virus (our vet is looking into getting him on
Interferon)? Are there any diet changes that can help? He doesn't like the
Felovite, are there any other options for getting him his vitamins? Anything
else I'm missing?

Many thanks,

Dave
