  == Effect on Other Animals? ==  I noticed in the article that there is no mention of the device's effect on non-human animals. This is something I was genuinely curious about when reading the article: presumably animals such as dogs find the device's sound at least as unpleasant as the young people it is used to disperse. Is anyone aware of any research done into this, or have any anecdotal evidence of relevance?  My family considered buying a Mosquito a few years back to deter loiterers behind their house, and had a dog at the time, so this is something I've always wondered about.
