There are many reasons why pets are not allowed in university dormitories. First of all, if the cleaning staff is lazy or careless, pet feces will not only stink up the dormitory, but also cause an outbreak of plague, especially in a crowded place like university dormitory. If a plague breaks out in a large area, it will be fatal to public opinion and students' sense of security to society. Secondly, not everyone knows how to keep pets scientifically. Pets need to be cleaned regularly, and their excreta should also be cleaned regularly. If not handled properly, they can spread bacteria or parasites. School dormitory is a densely populated public space, and once the disease spreads, the consequences are unimaginable. Finally, the most basic condition of university dormitory management is to manage the safety and cleanliness of students living in dormitories. Keeping pets destroyed safety and cleanliness, and the safety and hygiene problems that occurred at that time were the responsibility that the school could not bear.
