Is someone else in the room?
Your cat's fur stands on end; they stare at an empty corner and follow something invisible with their eyes. Guardians of the threshold, or biological precision? We explore the science behind cats' creepiest behavior.
Ultraviolet vision
Cats can perceive part of the ultraviolet spectrum. What looks like empty air to you is, for them, full of glowing particles and trails of light that we can't perceive. They aren't seeing ghosts; they're seeing the radiation of the real world.
Ultrasonic hearing
Cats can detect frequencies of up to 64,000 Hz. They can hear a mouse breathing behind the wall or the hum of electricity in your outlets. When they seem to be focusing on "nothing," they're actually tuning in to sounds you can't even imagine.
