The name "KI-YI" was derived from the sound that an injured dog makes. Our KI-YI also produces the raspy, distress calls of prey, which appeals to all predators. This call has a removable mouthpiece which can be used alone to produce the various pitches ranging from fawn distress calls, pup whines to rabbit screams. It is easy to use and is small which makes it great for compact carrying. The shrill wake-up calls of the KI-YI will definitely get their attention. Includes instructional mini CD.
