It’s difficult to know what to make of the Croydon cat killer story.
Initially, people from London-area cat rescues said they were looking for a person who had mutilated dozens of cats in the South London area. As the number increased to more than 100 and public outrage became palpable, police opened an investigation.
The story was wild. Newspapers bandied about disturbing figures, claiming hundreds of cats mutilated at the hands of a sick individual or several people. There were reports of feline remains artfully arranged in the driveways and on the front steps of victims’ homes to inflict maximum trauma on the people who discovered them, with allegedly clean cuts indicating a human with a blade was responsible.
Then in 2021, the Metropolitan Police announced they were closing their case after three years and almost $200,000 spent.
Foxes, not cruel humans, were responsible for the cat killings, they said. A study in the journal Veterinary Pathology found fox DNA on the corpses of 32 cats and said puncture wounds on the feline bodies were consistent with fox bites.
London-area animal rescues disputed the findings, saying the study couldn’t account for the mutilation of so many animals. The study’s authors blamed “badly behaved foxes” who were scavenging on the remains of strays and pets killed in traffic or by ingesting antifreeze.

Lots of other people refused to accept the Metropolitan Police conclusion, including people whose cats had been victimized. In some of those cases, veterinarians concluded the cats were killed by humans, not animals.
Which brings us to now.
The Mirror has teamed up with the South London Animal Rights Network (SLAIN) to create an interactive map showing the locations where more than 1,000 dead cats were found over the past several years.
“This map shows where incidents have occurred but also and perhaps just as important, where incidents have never happened,” SLAIN’s Boudicca Rising told the paper. “If you know of someone who made journeys to these locations on these dates please do get in touch with us. All information will be treated in the strictest of confidence.”
Documents obtained by journalists in London indicate there was internal tension at the Metropolitan Police over the resources that had been allocated to the cat case, and spokesperson for the force admitted that was a consideration. But the department stands by its assessment and says there’s no evidence a serial cat killer is on the loose.
It’s difficult to believe someone or a group of people could evade capture while allegedly killing more than 1,000 cats since 2015, especially in a city like London where CCTV cameras blanket most neighborhoods.
There are an estimated one million CCTV cameras covering 607 square miles of London, and the commonly-cited statistic claims Londoners are caught on CCTV cameras an average of 300 times per day. Other estimates claim that number is too high, and the average UK citizen is spotted on a municipal surveillance camera 70 times a day.
Notably, those figures do not include private cameras like Ring systems and surveillance operated by private businesses. The point is, it’s very difficult to avoid cameras in London, and if there are human feline killers out there, they must know an awful lot about where the cameras are.
If the phantom cat-killers are real, not only have they been able to avoid appearing on surveillance, they’ve evaded the watchful eyes of neighbors as the story circulated widely in the press. The theory that the killings were the work of animals, mostly under the cover of night and beneath the notice of people, sounded more plausible to many people.
Still, the theory doesn’t neatly fit the evidence.
Not all veterinarians agree that foxes are the culprit. While the veterinary pathologists who authored the study looked at photographs of the mutilated felines, some veterinarians who directly examined the bodies of slain cats concluded they were killed with blades. When experts are at odds over evidence, what can you do but gather more information and hope for the best?
London may have to do what Washington, D.C. did and deploy low-to-the-ground trail cameras and regular surveillance cameras around the city. In Washington, the goal was to get an accurate census on the number of strays and ferals living within city limits. In London, a census could be a bonus as they finally get an answer to the question of who’s been killing all those cats.
