Revamped Rough Animatic

Hey guys,

I've been thinking about my senior project and I've decided that I'm not sold on my Morning Stretch idea. I like the concept of a cat getting stuck on a garage door, but I don't think Morning Stretch was the best execution. In anthropology class I thought, what if a cat gets stuck going through the garage door? That way we can see his face rather than his back the entire time. I threw together a rough animatic and I like the new version 100% more than Morning Stretch.

My only problem is, I wanted the cat to respond to the fact that the garage door is about to open before it actually does. That way he'll already be struggling to escape as it starts to life him. My other problem is the fact that the garage door sound starts a bit before the cat actually starts to go up. Once I figure out what tips the cat off on what's about to happen, I imagine I'll be able to just move the garage door sound back to when he starts to lift from the ground.

Does anyone have any ideas of what the cat can respond to that will cause him to struggle desperately in preparation for the door to open?
