Voted “other” because I have several. Two are so social that one of them will literally come up and lick visiting cable guys on the head (yes, it was quite charming–and he liked cats, thank goodness!) and a couple you won’t even see a glimpse of until you’ve visited us several times. The others are halfway in between. They’ll get curious and want to see what’s going on so they’ll venture out, but they won’t get too close to anybody until they’re familiar.
