this is an old myth that continues to make the rounds. the FeLV virus does not, and cannot, cause a cat to become positive. in fact, there is anecdotal evidence on this list, that vaccinating a truly positive FeLV increases their lifespan!
(anyone on this list also on Fan-H? gloria, maybe? there was just a discussion on the differences between the kinds of vaccines that looked really good--i don't have the time right now to go grab all the discussion.....) as for the FIV vaccine, it doesn't cause FIV either, it just produces antibodies that will make the cat TEST positive on both the SNAP and Western Blot test. bless that vet who realizes this (tho all should), and insists upon identifying the cat's reason for a positive test!
