In an opening scene redolent of Kubrick's A Clockwork Orange (1971), six masked youths vandalise the property of a wealthy married couple; when the owners arrive home to discover the hoodlums still at work, the husband is forced to watch as his wife is stripped and gang-raped. Uncompromising Amsterdam detective Van der Valk (Bryan Marshall) investigates the case, and comes to suspect a group of privileged teenagers called The Ravens, whose search for kicks has led them to be exploited by a Charles Manson-style svengali.Because Of The Cats is a little sluggish at times, but its gritty realism will most likely keep fans of Euro-crime films and '70s exploitation more than happy. The initial sexual assault is graphically depicted in all of its ugliness, there's a smidgen of violence, and, with this being a Dutch film, we also get full frontal nudity from both sexes. Eagle-eyed viewers might even recognise Sylvia Kristel of Emmanuelle fame as one of the 'Cats', the elite girls who associate with The Ravens, and who provide the film with its most memorable scene, a spot of night-time skinny dipping that turns to murder.6.5 out of 10, rounded up to 7 for IMDb.

This slightly odd thriller is another of the early 70's movies which played upon the fears generated by the Manson Family murders of 1969. These 'counter-culture gone bad' movies often focus on cult groups who commit crimes and this movie is no different in this regard. Set in Amsterdam, a detective investigates a series of vicious house invasions committed by a gang of rich youths. They don't need money, so the source of their crimes turns out to be cult based.Opening with a disturbing attack on a married couple where the woman is gang raped while the husband is forced to helplessly look on, this is a movie which doesn't pull its punches. Its sexual frankness is at least partially down to its Dutch origins I am guessing, seeing as this nation was, and remains, one of the most sexually liberated in the world. This results in a film with a great deal of matter-of-fact full-frontal nudity throughout but also the graphic opening attack sequence. So the film definitely falls into the exploitation bracket, although it isn't all that excessive beyond this particular scene. It soon afterwards boils down to a detective story running parallel to one detailing the dramas surrounding the criminal youths. It's not in all honesty all that dynamically told to tell you the truth and it is a little uneventful overall. I thought also that the whole cult side of the story could have been magnified more, as this type of thing never really gets old but it was underplayed here somewhat. Still, this is still a reasonably distinctive film, probably mainly on account of it being a counter-culture themed film from the Netherlands, which is not exactly the norm. Definitely worth a watch but it's nothing too essential.

It has been said of the 1960s, if you can remember them, you weren't really there; the same has on occasion been said of the 1970s. This film dates from 1973, and I must have been there because I watched it on Monday and didn't remember it, although shortly before he uttered them, I repeated the villain's last words verbatim – words that can't be repeated here.I'd probably forgotten "Because Of The Cats" not because of the passage of 4 decades, but because it is such rubbish.This is an off-beat film, even for the 1970s; the gang rape scene at the beginning is both extremely graphic and very realistic, but not really necessary; the gratuitous male nudity is inexcusable, as is the wooden dialogue. As for the terrible plot...was any police investigation in the UK, Holland or anywhere ever conducted like this? There was no DNA in the 70s, but the same cannot be said for fingerprints.And the detective, this is not the Van De Valk I remember from the TV series. Unless you have an unhealthy fascination for pubic hair and/or male genitalia, give this one a miss.

In what seems to almost come out of today's headlines.....a group of rich boys decide to rape and terrorize people for a goof.They rape middle-aged women in their own house while forcing their husbands to see it all. All this while destroying their personal property. You see paintings get slashed, furniture get ripped up, and personal items smashed just for the fun of it. And these are valuable items. And the rape scenes may be hard to watch for some.Then we get a police drama. The inspector in question targets the group for imprisonment. We see a lot of technical details about police work. Euro-flicks like to do that it seems. (Remember "Man on the Roof?") These bits almost play like a documentary.The pace seems to get slower as we move on, but the intriguing characters keep it in focus. And the culprits are almost likable despite their sliminess. This film is hard to find. But worth a look. The director Fons Radermakers (spelling?) later won a Foreign Film Oscar for "The Amateur."
