Don’t F**k with Cats: Hunting an Internet Killer is a new Netflix true-crime documentary series. It’s just three episodes which makes it a very quick binge. Also, it’s pretty damn brilliant and has the most awesome ending. Read our full Don’t F**k with Cats review here!

Don’t F**k with Cats: Hunting an Internet Killer is a Netflix documentary series in three parts. It features some rather wonderful self-confessed “Internet nerds” who manage to identify a man killing cats and posting videos about it.

You might know the story already – especially if you’re Canadian – but I still think this should be a fascinating watch. If you’re not familiar with the name Luka Magnotta, then this is the story about this creepy psycho.

Continue reading our Don’t F**k with Cats review below. Minor spoilers may occur since this documentary is about a true crime, which we will be mentioning as well.

Internet nerds to the rescue

To begin with, the Internet nerds are all about trying to find this guy because he kills cats and laughs about it. However, they do quickly begin to fear that this guy will move on to killing people. Unfortunately, they have a hard time getting through to the police with this information.

Okay, I suppose you can’t really blame the police, but then again, this particular case has a lot of evidence. And it is a well-known and established fact that many serial killers do start out hurting animals. I mean, even in the Netflix series Mindhunter this is a big part of basic profiling.

Anyway, it turns out the Internet nerds were right in their fearful assumptions. In other words, this Netflix series starts out being about the videos featuring cats being killed. However, it ends up being a worldwide manhunt for a murderer when the murder is also shown in a video online.

Animal versus human killings

I should also mention that I know a lot of people will be angry and annoyed with the fact that people cry over cats and dogs being killed. Especially when a human being is also killed. However, the big difference is with the fact that the animals are completely helpless and trust us humans.

That’s not to say their lives matter more, but they are at our mercy. And when we betray their trust and our power, it does reminds us of other situation where this occurs. It could be children or elderly being harmed. 

Finally, if you read my little author profile at the bottom of this page, you will know that my pet peeve is killing animals for shock value. I do absolutely loathe animals being harmed. In other words, the internet nerds hunting down this psycho are my people!

The ending of Don’t F**k with Cats: Hunting an Internet Killer

Since this is a documentary, you really don’t need the ending explained. I do, however, want to mention that the ending of this Netflix docu-series is immensely satisfying. Especially since we get to the very end of the story which includes the killer (of both cats, dogs and a person) being caught and convicted.

Also, the very final scene of Don’t F**k with Cats: Hunting an Internet Killer is simply brilliant. It asks a very important and relevant question. I love watching documentaries and stories about serial killers and true crime. Still, I also wonder if maybe all these movies and documentaries are feeding the fire.

Many serial killers are vain and narcicistic people who want people to know and fear them. And yet, they also tend to get a lot of fans and admirers. That particular side of the serial killer fascination absolutely disgusts me.

Watch Don’t F**k with Cats on Netflix now!

This new Netflix docu-series was written and directed by Mark Lewis. He is already quite experienced with the darker side of the internet. He also wrote and directed the documentary Silk Road: Drugs, Death and the Dark Web from 2017.

Don’t F**k with Cats: Hunting an Internet Killer is one of the tightest documentary series on Netflix. With just three episodes, the story is told in a very chronological and intense way. You will probably be both surprised and angry. However, don’t fear, the  ending is very satisfying.

Also, that final scene of this Netflix documentary is downright brilliant!

Don’t F**k with Cats: Hunting an Internet Killer is out on Netflix worldwide from December 18, 2019.


The Docu Series tells the story of how a group of amateur online sleuths launched a manhunt for Luka Magnotta, who gained attention for posting a video of himself killing two kittens. Encouraged by his growing notoriety, the Canadian later murdered Chinese student Jun Lin in grisly circumstances.

I write reviews and recaps on Heaven of Horror. And yes, it does happen that I find myself screaming, when watching a good horror movie. I love psychological horror, survival horror and kick-ass women. Also, I have a huge soft spot for a good horror-comedy. Oh yeah, and I absolutely HATE when animals are harmed in movies, so I will immediately think less of any movie, where animals are harmed for entertainment (even if the animals are just really good actors). Fortunately, horror doesn't use this nearly as much as comedy. And people assume horror lovers are the messed up ones. Go figure!
