I have been doing some research this morning trying to figure out what happened to Simon in the end. I came across this case study which has information, in very technical language, about why many cats with FeLV get anemia.
http://www.bloodline.net/stories/storyReader$2338 Actually, it describes the processes by which they become anemic, but says the reason is unknown. It also says that clinical symptoms of FeLV vary by strain and subgroup, as well as by environmental factors. It also says that 30% of cats with FeLV who get lymphoma have it metastisized in the bone marrow. No one else on the lymphoma list serve seems to have a cat who got it in the bone marrow, which is stage V, the last stage, and so I have been feeling like I just caught it late with Simon. I think I did miss early signs and catch it late (that's clear, actually, since he was very jaundiced when I brought him in and I had not noticed that), but it may also have to do with the fact that there are hardly any positive cats on that list serve (why, i don't know).
