|When a cat is exposed to the feline leukemia virus (FeLV), the cat might have a transient infection and fight it off, developing immunity — some vets say that up to 70 percent of adult cats survive exposure this way. If the cat doesn’t overcome the initial infection, the virus will move to the bone marrow and the cat will be persistently infected. And finally, the cat may continue to harbor the virus, thereby becoming a carrier.
Many latently infected cats actually become free of the virus after a few years, but others become persistently infected. Cats that test positive should be retested 12 weeks later to confirm the diagnosis.
