I think I met Prometheus, actually. He was going under the name of Sampson at the time. He lived with some good friends of ours in upper New York State. About once a year we'd get together with them and bring out some lobster and they'd provide steak. He was the only cat there who was completely uninterested in the lobbies-- he wanted broiled cow. We used to joke that he was the Mafia hit-man of the cat neighborhood.
My Raven, on the other hand, was really a black lab (Labrador Retriever) in a cat's body. Only cat I ever met who had a guilty conscience (or any other kind of conscience, really.) Stomach cancer got him a few years ago.
