It's obviously very mild calici and if bilbo hasn't picked it up yet then maybe he won't at all x

There is only a short period of time that the cats will shed it for and then if carriers it's usually brought on again by a lot of stress x

There's such a large amount of cats that have these things in their system unfortunately, until they can find a cure for it all we can do is wait x however even then with so many strains of the virus it would be very hard to cure them all i'm sure - but at least it would be a start x
