Hmmm....as I was reading this thread I thought that I would like to get some of these frogs. Up until the point I read your post. Thanks for the heads up. The things you may not know until you get the frogs. Yikes!!!Don't put them anywhere near a bedroom or living space where you will be able to hear them. My group calls ALL day and you can hear it from the basement all the way up a flight of stairs to the other end of the house in the kitchen while the T.V. is on.
