Cats are famously sneaky; there’s a reason why particularly stealthy burglars are called cat burglars.

A group of Japanese office workers were reminded of this fact when a cat unexpectedly targeted their office.

This sneaky kitty wasn’t stealing, though. He was using his stealth for something else: surveillance.

The kitty’s surveillance plot was discovered when an office worker unexpectedly noticed that a small face was staring down at him through an opening in the ceiling.
