Netflix is now, if not before, well-known for its continuously upkept true crime tastes, with not even the increasingly populated genre slowing them down. For May 2026, the streamer has come forth with yet another never-before-touched-upon, atypical real-life crime event, one committed against cats. The result is Don't F**k with Cats: Hunting an Internet Killer, a chilling true crime docuseries that plunges viewers into a real-life nightmare of online cruelty, obsession, and a killer who weaponizes the internet for attention. 

But what exactly went down for it to have Netflix's eye? 

Netflix’s Don't F**k with Cats: Hunting an Internet Killer is a three-part true crime documentary that follows an online group of amateur sleuths, including animal lover and activist Deanna Thompson, as they attempt to track down a man behind a series of disturbing animal cruelty videos. The case centres on Luka Magnotta, a Canadian adult actor who posts graphic clips of killing kittens, sparking outrage and pushing viewers to act. The series documents how the group analyzes clues across usernames, IP traces, and visual details hidden in the footage, slowly narrowing in on Magnotta.

As the investigation unfolds, he continues to taunt the internet with escalating content, turning the chase into a psychological game. The story ultimately shifts to the real-world murder of Jun Lin, linking the online behavior to a far more serious crime and raising ethical questions about digital vigilance and attention-driven violence.
