"Do you live in an earthquake-prone area?"

Southern Ohio does have quakes every once in awhile but they are very mild and very rare.

In that case, I would say that the possibility of an influx of coyotes, or some other wild predator is very possible.

2009 Earthquake Probability Mapping

Earthquakes are known to generate electromagnetic fields and some odors resulting from the piezoelectric properties of the crystals in the minerals in the ground. They then couple with the atmospheric weather system and the Earth’s geomagnetic field. Many animals can feel these electromagnetic fields and some can smell the change in odors.

Another possibility has been some Solar storms and a Coronal Mass Ejection (CME) event on the Farside of the Sun as of yesterday.
