It’s an almost universal behavior across our feline friends. Your cat sits at the door, meowing for someone to open it, and then you open it and he’s instantly meowing for somebody to open it again.
Here’s a video you might like: A cat owner attempted to avoid his cat from opening his bedroom door by placing a large bucket of water before the door– however the cat’s determination is far too strong.
It’s since cats are territorial and hate shut doors.
When cats are meowing or pawing at a door, they most of the time are asking you to open the door and leave it open.
They could not intend to travel outside (or inside) the room, however they choose not to have any one of their territory blocked off. If you let them through and shut it again, they’ll often just do the same routine from the other side of the door no matter which side you put them on.
Because of their territorial nature, cats think they in fact have your house. When you close a door, it is no surprise that lots of cats will certainly attempt to open, scratch, or attack it in every single way. They may simply find your effort to shut a door as a sign that undermines their absolute reign of the territory.
