Today, I was studying when a tremendous crash of glass sounded from the other room. Was it a burglar? Nope. The cat had tried to jump from the kitchen table to the top of the cabinet, missed, and slammed into the cabinet's glass door. FML
OP here. My cat was not hurt, thankfully. He briefly looked a bit shaken, and then felt the need to be underfoot while I cleaned up the glass. He's made that jump before and since, though nowadays a tall cat tree seems to satisfy his desire to launch himself to great heights.
