got roadkilled yesterday. I know this because I saw it on the street in front of my house all bloody and stuff. Should I send him a card? 
Dead cats can't read cards. In fact, living cats can't either.
You've got my condolences.
I once saw a dead cat on the road too. There was a crow sitting on top of it. Few moments later there were a dead cat AND a dead crow on the road. Hmmm
