I'm glad that things worked out for the majority of you, but IMO, if I'm going to err, I'd rather it be on the side of caution. At least if something goes wrong (which it shouldn't with a dead virus, correct?) it won't be because I didn't follow my breeder's advise. I can't imagine the pain it causes a breeder to entrust their kitten to someone who goes against their instruction, and God forbid, loses the kitten for whatever reason. We all have a huge emotional investment in our SVs and face it, monetary too, when you think about vet bills, entertainment, comfort, etc. I wouldn't be able to forgive myself if a decision of mine caused me to lose my beautiful boy. I'm not saying that other breeders aren't giving sound advice to new owners; I'm just saying that this is what my breeder told me, and I will follow her instruction to the letter, as any breeder would want their purchaser to do.
You need to follow your breeder's advice...you will probably not get any consensus on the MLV vs Killed question anyway
