http://www.rpoutdoors.com/tapes.html Did a web search and saw these for sale...don't know if the bobcat / lion are out of stock or discontinued. It may be worth making a call to Johnny Stewart or a store selling the tapes.
Would it be possible to play free sounds digital sounds on the computer and capture them on a tape recorder for playback on the caller?
Varmint Al's web site has a library of sounds that can be downloaded for free, I'd bet there are other sites with the sounds your looking for.
good luck
