My cat, Bonkers, got into his catnip bag again. He gets his face into it and then runs up and down the hall in my apartment, like he was shot out of a cannon, pushing my carpets up the wall and knocking shit over. When he's done, he collapses, and looks like this for an hour or two. I poked him with my Swifter a few times, just to make sure he wasn't dead.
