Dag- I've only had a med. cat twice: Once in SnakeClan (I think it was Snake) a looooong time ago and Blackmoon of MoonClan (or ThunderClan now) xD I thought Blue had Wolf med O.o
And as for Fear, it doesn't really matter whether they have one or not. Because of Fear's mood towards being independent, that might go against healing too (a "tough it out and walk it off" type thing) But, I'll only make it that way if no one wants med. there, and if they do, it'll probably just be a warrior with extensive knowledge of herbs and such
Like the deputy position, if someone does have a med. cat in Fear though, they get to have the one in Silent too, if they want. If not, then it's up for grabs, cus Silent is having one xD Again, preferably they use a different cat for med cat in Silent then they did Fear though xP
