You can't. Every school has clear rules and regulations on dormitory hygiene, and it is forbidden to keep pets in the dormitory. The punishment for keeping pets is also very serious. Because the rooms in each dormitory are very small, pets coming in will make the sanitary environment of the dormitory worse and make students sick for a long time. If pets slip out of the dormitory, it will also have a great impact on the order of the dormitory. Therefore, it is not recommended to keep cats in the dormitory.
