Yes, that is completely normal. They shed their whiskers and usually you will only find the really long, big ones. They get caught in my carpet and I have to pull them out because the vacuum doesn't always get them for some reason.
Perfectly normal. They don't lose them very often, and I think most of the time we miss them.
I bet Lynn will chime in on her love of whiskers, I think she collects them! We have fun at shows spotting the occasional whisker a chin drops and running up to grab it. :dance3:
