Typical course of a dying FELV kitty?

[Beckie McRae]

I think the Moeman is dying.

I'm just trying to keep him comfortable as possible now.  No more pokes
and prods, etc.  He's content I think.  I'm just wondering if you guys
could tell me the typical course of dying for a FELV cat?  Will he just
get weaker and weaker like he has been?
