Casper the Commuting Cat

Fester Cat once read a book where a cat travelled around on buses, until a taxi driver accidentally runs the cat over. The owner had many cats, and had many regrets about the cat that died, and the cat sent letters to the owner from on top of a Rainbow bridge, in a sort of heaven. (PROSE: The Story of Fester Cat)
