# Don't F**k with Cats: Hunting an Internet Killer

Don't F**k with Cats: Hunting an Internet Killer is a 2019 true crime docuseries about an online manhunt. It is written and directed by Mark Lewis and was released on Netflix on December 18, 2019. The series chronicles events following a crowd-sourced amateur investigation into a series of animal cruelty acts committed by Canadian pornographic actor Luka Magnotta, culminating in his murder of Jun Lin, a student from China who was studying at Concordia University. It was one of Netflix's Top 5 most-watched documentaries of 2019.

## Premise

The three-part docuseries follows a group of amateur internet sleuths who launched a manhunt for Luka Magnotta after he gained international notoriety in 2010 for sharing a video online of himself killing two kittens in a plastic bag by suffocating them with a vacuum cleaner. Magnotta was later convicted for murdering Jun Lin in grisly circumstances in 2012.

## Early investigation

The series started with Deanna Thompson, a data analyst for a casino in Las Vegas, and John Green, from Los Angeles. In 2010, a viral video called 1 boy 2 kittens was linked on Facebook and posted on YouTube. The video shows a man playing with two kittens before he puts them in a very tight vacuum seal bag and vacuums out the air, suffocating the kittens. Thompson and Green subsequently started a Facebook group to build evidence and find the perpetrator. The group worked together to examine the details of the video, including the objects in the room, to help solve the mystery.

## Impact

In the trial for the 2021 murder of Jorge Martin Carreno, prosecutors provided video and audio evidence of the defendant, Scarlet Blake, livestreaming the killing and dissecting of a cat, with the New Order song "True Faith" playing in the background; they said the defendant's use of the song was in homage to the docuseries Don't F*** With Cats. Blake was sentenced to life imprisonment for the murder. At her sentencing hearing, Mr Justice Chamberlain told Blake "[the] documentary played a part in your own mind in the link between killing a cat and killing a person."
Deanna Thompson, one of the lead presenters of the docuseries, later appeared as a contestant on the seventh season of The Mole in 2024.
