Cats keep wanting to enter the room and purring when the door is closed. This may be because they are interested in the environment, smell or objects in the room, or they want the attention and companionship of their owners. Here are some suggestions to help you deal with this situation: Understand your cat’s needs: Your cat may want to come into the room because of reasons such as curiosity, loneliness, or hunger. Observe your cat's behavior and meows, try to understand its needs, and try to meet them. Provide cats with adequate attention: Cats are social animals and they need their owners’ company and attention. In daily life, interact more with cats and provide them with toys, cat climbing frames and other entertainment facilities to meet their spiritual needs.

Set a special resting area for the cat: Set up a comfortable and quiet resting area for the cat outside the room area to make it feel safe and content. In this way, even if the cat cannot enter the room, it can still have a good resting environment.

Train the cat to adapt to closing the door: Through gradual training, let the cat adapt to the situation of the room door being closed. At first, you can close the door briefly and then gradually extend the closing time. During the training process, give the cat appropriate rewards and encouragement to help it gradually adapt.
