I live in Sedro Woolley, I just got back from Mazama. Sorry for the confusion.
I've never seen a fox on the mainland here, only on the San Juans, But thats interesting you say that because a neighbor I talked to said a "fox" had a den nearby, I took that as coyote.
But they also said there have been cougar sightings recently. I live in city limits. I put game cameras out tonight to see if it shows up.
