Cat or Earthquake?
This happened some time ago. I heard a cascading crash from the direction of the kitchen, and Klickitat ran past me down the hall and hid under the bed -- the first time he'd ever done something so bad he felt the need to hide. Normally he'll do something bad right in front of you and not care. I went into the kitchen to find the counter and floor covered in broken glass. I then had to go drag Klick out from under the bed to make sure he was ok (he was) before starting the cleanup effort.
Our theory is this: we used to keep the cat food bowls up there in the same cabinet, maybe he decided to go see if the cat food was up there too. So he climbed in and probably shoved his way behind the glasses looking. Probably one fell and broke and he panicked, knocking the rest of them out as he made his escape. Of the dozen glasses I think only 2 or 3 survived.
