Police in the United Kingdom and Ireland have been compelled to address public fears stemming from viral TikTok videos that appeared to show a menacing "killer" Cat in the Hat character lurking in streets. Authorities have confirmed that these videos are AI-generated hoaxes and do not represent a genuine threat.
The fabricated videos, featuring a figure dressed as the Dr. Seuss character, gained widespread attention on TikTok, prompting some young people in the UK and Ireland to believe a real danger was present. The situation drew comparisons to the 2016 "killer clown" trend, which saw false rumors of organized violence spread rapidly online.
After investigating the reports, police concluded that the videos were created using artificial intelligence. The clips were shared across numerous accounts, many of which were newly created. One video, showing a person in the Cat in the Hat costume with the caption "Help, what do I do?", garnered 15 million views in just three weeks.
Some videos included explicit threats to specific areas, such as a post warning "Kent I'm coming. Lock your doors." Other clips appeared to show the figure approaching front doors, as if captured by ring doorbell cameras.
A 16-year-old named Skye described her fear during a sleepover, stating, "I was having a sleepover but everyone started watching Cat in the Hat videos. It was 3am. I wanted to go home. When I started walking down my friends' driveway, I got totally freaked out that the Cat in the Hat was going to jump out. I had to call my mum to pick me up."
The phenomenon was particularly concentrated in the Irish counties of Limerick and Wexford. Local Gardaí in Wexford swiftly dismissed the sightings as fake, confirming the images were AI-generated. A statement from the force read, "In an unusual turn of events we are hearing a lot about an illusive Dr Seuss character doing the rounds online, apparently causing havoc in neighbourhoods and towns across the country. Fortunately, we can rule out the issue, which is essentially an AI prompt that places the character into images/videos of familiar places. To be clear, the Cat in the Hat was not in your driveway while you were out and he is not currently hiding out in Curracloe."
The rumors subsequently spread to England. South Yorkshire Police addressed claims of a "killer Cat in the Hat" sighting that originated from a fabricated Facebook post. A message from a non-existent force called "Yorkshire Police" suggested that authorities were taking the sightings seriously.
The fake post claimed: "Officers are aware of a number of reports regarding a suspicious figure described as a 'cat in the hat' seen walking in the Meadowhall area at approximately 2:30am this morning. A member of the public in the area took the below photo and has forwarded it to us. We are taking this matter seriously, and extra patrols are in the area. While there is no cause for alarm at this time, we are asking everyone to remain vigilant."
The actual South Yorkshire Police responded by advising the public to verify the authenticity of online posts providing policing updates. They stated, "The cat is not out of the hat on this one… Please don't believe everything you read on social media." The force confirmed there were no reports of a "cat in a hat" in Meadowhall or elsewhere in South Yorkshire, and also noted the absence of any sightings of "Thing One and Thing Two."
