You've probably seen the video taken of a flock of turkeys marching in a circle around a dead cat. It is thought that they are simply following each other to no end, as lines of ants occasionally do.
And sometimes such a thing is so visually fascinating, and sometimes a deadline seems to pop out of nowhere, and when deadlines exist, there IS no "waiting until inspiration strikes."
You can't wait for inspiration. You (usually) can't wander into a day job and get to work only when you feel like it (unfortunately). An art journal is a good spot to illustrate a news event! What would probably be forgotten a few weeks from now is now a permanent little morbid visual record.
BY THE WAY. If you're worried about how to cartoon a cat to look dead and not just sleeping, resist the urge to google pictures of dead cats for a quick pose reference. It's not worth it! D:
