No cats are shown being harmed in this film. Votes implying there is may have mistaken this page for that of the franchise’s first film, “The Collector”.
No animal other than a dog is shown dying on-screen. There is a room filled with taxidermy or skeletons of various wild animals (foxes, raccoons, etc.).
A character’s arm breaks visibly and audibly after jumping out of a window to escape. In order to escape a trap later in the film, this character re-breaks his arm and then re-sets it with audible crunches and visual effects.
The film begins with a character discovering her partner (?) making out with another girl. He shrugs at her and she punches him in the face before storming away.
There are bloody tally marks carved into someone’s arm. They are shown on more than one occasion and were self-inflicted to serve as necessary navigational clues. There are also scenes with a razorblade being used to inflict cuts onto a victim by the killer, as well as someone trapped in a net lined with them. The room is decorated with razorblade-lined wires. This may be triggering to individuals sensitive to this imagery
If torture is an upsetting topic for any viewers, it would likely be best to avoid this film! It is wholly centered around torture of victims (either directly by a killer or by the means of elaborate traps).
While it is not actively shown, a man is shown on the roof of a car (presumably fallen to his death from the window above). Additionally, a character jumps from a window and breaks his arm (but does not die from the fall).
