Danny,
I hit a Kangaroo once (I was only going slow though [KE30 days], because I knew they'd be out along this stretch of road that I used to frequent).
I got out to check the car, but knew it'd be fine. I was only doing around 50kmph. Saw the Roo, thought I'd better see if it was alive or dead. He was fine. Now, I 'knew' he was fine, because he jumped up as I approached, ran up to me, and kicked the living **** out of me.
Be careful dude, Karma is rife these days
