I think we have either a family of foxes or a lonely fox looking for love living in the woods nearby. Last night, around midnight, I heard something that sounded like a pug with a chest cold, so I went out to investigate. About a month ago, I saw a reddish flash disappear into our neighbor's yard, and this, coupled with the sounds described above, lead me to believe that yes, we do have foxes living in the neighborhood.
I'm not really bothered by this, mostly because they're not likely to be too pesky. We have an enormous dog who makes a lot of noise, so they probably won't come too close to the house; our indoor/outdoor cat, on the other hand, needs to start staying closer to home, just in case someone's desperate for a meal.
I'm considering calling the local DNR guys again, because someone told me red foxes are endangered in the US. Wikipedia says they're listed as "least concern", so maybe I'll eschew calling DNR, particualrly since I'm not sure that the local guy will react with any more enthusiasm than he did when I asked about turtle conservation. Some conservation officer you are, mister! Maybe he should consider going into a different field. Humph.
Still, I take the appearance of foxes to be a good omen.
