Cats like to stay around when their owners go to the toilet, mainly because cats are very curious and want to know what their owners are doing in the toilet. Secondly, it may be because cats have a strong sense of territory and feel that the toilet is also their territory. In addition, it may be because cats are highly dependent and gregarious, so they will follow their owners wherever they go. If the owner doesn't like the cat to follow him to the toilet, he can just close the toilet door.

　1. Curiosity

Cats are animals with a strong sense of curiosity, and cats are also relatively independent. When the owner is at home, the cat will quietly hide and observe what the owner is doing, especially if the owner is not in the cat's sight. Cats are very curious about what the owner is doing. So when the owner goes to the toilet, the cat will feel that the owner is doing something inside, and then it will guard the door of the toilet.

　2. Territorial awareness

Cats have a strong sense of territory. They feel that their owner’s home is their territory, so when their owner goes to the toilet and closes the door, they will stand around and recognize the owner’s location.

3. Dependable

Cats are highly dependent and easily rely on their owners, so they want to follow their owners all the time. When the owner goes to the toilet and closes the door, the cat will guard outside. There are also some cats that bark wildly outside and scratch at the door because they cannot see the owner.

　4. Socially oriented

Cats like to travel together. In the relationship between cats, one cat acts as the leader. Once the leader does something, other cats will follow suit. The owner takes the lead when going to the toilet, so the cat will follow the owner to the toilet.
