Once a year, I have a lobster scoff. I had one cat that could hear the clerk take my money at the fish market on the other side of town when I bought lobster. I've seen cats keen for various types of food, but that cat, who was very well-trained and very well-mannered, would become viscious if the lobster wasn't coming fast enough.

I watched a documentary about cats in which cats were placed in complete darkness and still managed to catch mice. Now, that's acute hearing, aided by independant movement of the ears, allowing pinpointing almost as accurate as sight.
