I would tape the ears down and put in Carrier.

I made the mistake of letting one out in my suburban. It pissed the seat. I tried everything imaginable to get rid of the odor to include replacing the seat cushion recovering the seat. But the urine got into the steel frame. I sold the suburban.

You could also consider covering up the carrier and putting it far away from the engine.

Just thoughts.
