The reasons and solutions for cats that keep barking when they are not allowed into the bedroom:

1. Cats lack a sense of security and are clingy and need the company of their owners. The owner can also prepare a warm and comfortable nest for the cat outside, and hold the cat in the nest several times to let it know that this is a good place to sleep. Or put the nest in the bedroom first, and then move the nest out after the cat gets used to the nest.

2. The cat is full of energy and wants to play with its owner. Before entering the bedroom to rest every day, it is best to spend some time interacting and playing with it, or take it out for a walk to burn off energy. Try to meet the cat's needs. Cats should rest when they are tired from playing. This will also help keep the cat’s schedule consistent with its owner.

3. Feeling unfamiliar with the environment and want to find a familiar environment. Spend more time with the cat before going to bed, create a comfortable and warm nest for the cat, and guide the cat to go to the cat nest to rest more. The owner can also use some toys to distract its attention, such as cat food balls, electric mice, electric cat teasers, etc. According to your usual observation of cats, prepare more cats that cats like. The toys are for him to play with at night to attract his attention.
