Don't F**k with Cats: Hunting an Internet Killer (Season 1)

Don't F**k with Cats: Hunting an Internet Killer (2019) is Netflix's true crime documentary miniseries you can watch online on iFILM. Director Mark Lewis tracks the years-long hunt for a man who posted videos of animal cruelty online — a hunt that started with outraged strangers on Facebook and ended with an international murder investigation.

Deanna Thompson and John Green are at the centre of it: ordinary people with no law enforcement authority who decided the internet could find this guy faster than the police. And for a while, it could. But the more ground the amateur sleuths covered, the more the suspect seemed to feed off the attention — escalating from shocking videos to a homicide that crossed multiple borders.

Three episodes, built with the pacing of a thriller. The series raised lasting questions about vigilante justice online: what happens when public exposure becomes part of the crime? A British-American production, it became one of the most talked-about Netflix originals of its year. Stream Don't F**k with Cats (2019) online on iFILM.
