Can't find anything else on it.

Probably not worth the risk then. I just hope it will be easy to find the exact thing that I need at Radio Shack or an electronics store.

It could be a lifesaver for your cat, if it keeps her from chewing into a 120 volt cord. And maybe an alternative toy -- maybe something with catnip.You know I was just thinking of doing that. I had bought some jalapeno peppers in a jar with liquid and I was going to use that liquid but I like the idea of the cayene pepper better.
Thanks so much!
