...I think the few individuals who open yet another thread for the Cat of the Day do so inadvertently; out of their excitement, perhaps, for that day's cat, they may not have noticed that a thread for that particular cat already exists, before they start their thread for said cat. I find that most people in this forum stick to an unwritten rule (for lack of a better term) to first be certain that a thread for the cat of their choice had already been started, and then post a reply within that thread.

Personally I don't think you'd be hurting anyone's feelings by favoring one thread over another; in the wild frontier of the Internet, there's a heckuva lotta room for people to make mistakes and then learn from those mistakes. (And that's my two cents for the day.)
