How do I know he's immortal? Well when he was 3 we lived in LA. My commute was 1.5 hrs each way with a stop in Downtown for my wife. I drove a Jeep wrangler, mostly in bumper to bumper traffic. Well one day he decided to follow me out the door and sneak into the engine compartment. I had no idea. Drove to work with the stop in between. Luckily I parked somewhere covered when I got to work and stayed at the office for lunch.

Later I left and picked up my wife and was almost home when I hear meowing. I thought some stray got in there while my car was parked at work. Instead of stopping on the side of the road and risking it running into traffic we went all the way home. Jump out of the jeep and open the hood to see Orion, poking his head up and panting but unharmed. He saw where he was and ran for the house. If anything happened that day I would have thought he vanished in thin air. Why do they have to toy with us like that :D
