So a quick update.

I have done nothing... and in the past month have not had this happen (at least, not while I've been home). We have had the windows open every day since my last post since the weather has been BEAUTIFUL so I'd surely know if they were doing it. I'm either hoping the neighbor found a new place to walk her dogs, moved (we did have a vacancy recently and had new neighbors move in), or finally "got it".

Now the problem I'm having is, since it's so nice out and people are leaving their windows open, some neighbors have dogs that like to bark at the sound of a fly's fart... all day... and at all hours of the night... that isn't nearly as disrupting as the dogs that were barking in the window at my cats, however, so I'll take it.
