I usually don't blog about personal things, and write just about Wicket, or any new, Java related subject I'm excited about, but I'm breaking that habit for this time...

What is the fascination cats have with closed doors? Everytime we shut a door to keep the draft out, a cat immediately wants us to open that door. Sometimes she'll even grant you 5 minutes couch time, but I just think that is the time they need to realize the door has been shut.

Is there any scientific research being done on how long a cat can be in a (large) room with a closed door before she starts to scratch?
