In a household with animals indispensable ...

Totally annoyed by our cat, who has the property to open doors ajar until it stops, we decided for the clip Close door closers.
The acquisition is not cheap, but definitely pays off!
Installation is foolproof and takes place completely without damaging the doors.
After 2 days, rumors of our cats who have only done something, because it is something difficult to open the door, all have come to terms with. And the cold drafts stays outside.
The only drawback, as already mentioned in other reviews: after about 2 weeks, it squeaks like a haunted castle. But can be easily fixed with lubricant.
