Some of the cats begin moving about 10 seconds before any visible shaking can be seen in the footage.
The incident took place on June 18, when a 6.1 quake shook the Osaka region.
There have been reports over the years of some animals acting odd or fleeing earthquakes.
While it’s never been proved that animals can sense quakes before they strike, one theory is that they might feel very minor “p wave” shaking that would be imperceptible to humans.
In the video, a small crack can be heard just a few seconds into the clip that seems to get the cats’ attention and causes some to start running. Even the ones that don’t run perk up at the sound:
The full shaking begins about 10 seconds later.
Japan has an earthquake early warning system that pushes alerts and triggers alarms seconds before the shaking starts, so it’s also possible the cats heard something that wasn’t picked up by the camera’s microphone.
The cats in CAT Cafe CATchy and some of the nation’s other cat cafes are all rescues available for adoption, according to SoraNews 24.
