Japanese researchers have noted unusual behavior in mice exposed to electric and magnetic fields akin to those detected before earthquakes. This observation raises questions about the ability of various animals, including birds and potentially humans, to sense magnetic fields. Anecdotal evidence from forum participants includes a stray cat displaying hostility and a man's dogs acting erratically prior to an earthquake, suggesting a possible instinctual response to environmental changes. The discussion highlights curiosity about whether other animals, like dogs and snakes, also exhibit similar behaviors in response to impending seismic activity.
