hear fox growling, but there's no fox

I have opened the small section of land across the road. I have smelters lined up along the top side, next to the road, followed by the jewelry maker, with a storebought tree at the very end. Then there is a row of cherry trees, and then there are all of my crop fields. at the rightmost corner, if I press one of the cherry trees, I hear a fox growling. So I moved all of the trees out of the way, and press on the land, and hear a fox's growl.

But there is no fox there.

Not sure a screen shot would do much good!

I have my sound turned right down when I play, almost muted, so I didn't know foxes growled! Sounds a bit scary. Maybe it's actually a wolf, or a bear...
I wouldn't have the first clue how to do it, but maybe you could make a short video and post it? I am curious as to what is lurking on your land:unsure:

well, the 'fox' seems to have gone. no response when I poked around in the area this morning.
