Netflix’s 2019 three-part documentary Don’t F**k with Cats: Hunting an Internet Killer became a viral sensation for its chronicle of internet sleuths tracking down Luka Magnotta, a Canadian who posted videos of himself killing kittens before escalating to murder.
The Investigation
Amateur internet detectives on forums tracked Magnotta across years, analyzing video backgrounds, reflections, and metadata to identify him before he murdered Chinese student Jun Lin in 2012.
Why It Went Viral
- The title alone generated massive social media buzz
- Binge-worthy three-episode structure
- Raised questions about internet vigilantism
- Explored the dark side of viral fame-seeking
- Documentary aired 7 years after Magnotta’s arrest, allowing for complete storytelling
Controversy
Critics questioned whether the documentary itself contributed to the fame Magnotta craved. The series sparked debates about:
- Giving killers a platform
- Amateur sleuthing vs. law enforcement
- Internet culture’s role in criminal escalation
Cultural Impact
#DontFWithCats became shorthand for internet detective work and the power (and danger) of crowdsourced investigations. The phrase “don’t fuck with cats” became a cultural warning about internet mobs and obsessive online communities.
