Rat in car

There's a damn rat in my car. My sis was putting on her shoes inside the car when a rat jumped out and scooted off somewhere inside my car.

That was a few days ago and this morning when I got into my car, there was this smell. Doesn't take a rocket scientist to put two and two together to realise that Remy the rat must be dead and smelling.

Now, does anyone have any idea how to find the bloody thing. I fear it's somewhere inside the dashboard of my car.

I'm tempted to let my dog inside my car and see if he can sniff out the body.

Bugger.

UPDATE: Brought the car for servicing, they found two rats dead under the bonnet. One was inside the engine. They were in the middle of putrefaction.
