Viral images and videos purporting to show a life-sized version of the Cat in the Hat from Dr Seuss literature have sparked fear among teenagers in the UK and Ireland. Some young people have been convinced the character is real and could be encountered on the streets, leading police forces in both countries to issue statements confirming the images and videos are fabricated.

AI-generated images have predominantly focused on Irish counties including Limerick and Wexford, where shaky videos purportedly showed the character wandering through streets. Wexford's local police force quickly dismissed the sightings as fake and confirmed the images had been generated using artificial intelligence. South Yorkshire Police in England denied social media claims that a "killer Cat in the Hat" had been spotted in their area, which attracted hundreds of thousands of views on TikTok.

The trend appears to have accelerated following a post on August 8 by the pop culture site DiscussingFilm announcing that the original costume was being auctioned by Propstore, according to social media activity. The post garnered 10 million views, with comments describing the costume as "nightmare fuel" and "genuinely haunting." The lot is scheduled for sale as part of an auction of 1,400 pieces of film and TV memorabilia, with an estimated price of up to $24,000.

While many users have created parody videos and joky content featuring costumes and dances to popular music, some teenagers have reported genuine distress. A 16-year-old in Scotland said the trend reminded her of previous internet scares and that the character felt as if it "actually come to life to haunt me." Parents have also expressed concerns, with some comparing the phenomenon to past internet hoaxes.
