This Is Why Cats Are Never On The Right Side Of A Closed Door
If you have a cat at home you will surely know that your cat doesn’t want to see any of your doors closed.
As cats are territorial animals they like to undermine their territory. And when they see some door closed they want you to open the doors. They will wait for hours on the other side of the door ad if you open and then close it on the other side they will still meow and make you open the door.
So the main reason for such behavior is because in such a way they undermine their absolute reign of the territory.
