According to The Gary Post Tribune, Jeff Will, an associate professor of electrical and computer engineering at Valparaiso University, came up with the “Here Kitty, Kitty” app, for sale at iTunes for 99 cents, which plays sound that cats might find so appealing they come out from under the couch.
He figured if cats came out at the sound of a can opener, it would be nice to find other sounds that would make them come out, too, hence the idea for the app.
The app plays a can opener, another cat meowing, a bird chirping, a man calling for a cat, and even a dog barking.
