On a mission to uncover the reason behind his poor sleep, a man set up a camera near his bed to capture any unusual activity during the night.
Looking back at the footage, he discovered a simple yet surprising explanation for his sleep disturbances.
His cat had been sneaking into his room and sitting on his face while he was asleep, preventing him from breathing.
Photos of the man's findings were shared on Twitter, quickly going viral with over 1.4 million likes and 360,000 retweets.
Many people were concerned that the cat was trying to suffocate its owner, with some jokingly referring to it as a 'sleep catnea.'
However, others shared their own experiences of their pets' unusual behavior while they were asleep, including one person who woke up to find their cat staring at them dead in the eyes.
