high frequency piezo

I'm having a problem with stray cats, so I had the idea of using a PIR in conjunction with a high frequency piezo. I've read that cats will scramble away from frequencies above 25k. I'm new to electronics and the Basic Stamp world. Does this sound like a job that the basic stamp can handle and if so does anyone know of where I can get a high frequency piezo that the BS2 can work with?

Thanks in advance
