The hazards of keeping pets in college students' dormitories include polluting the environment, creating rabies, spreading parasites, affecting the harmony between roommates, creating allergens, consuming time and causing injuries. Domestic colleges and universities explicitly prohibit keeping pets in dormitories, and must strictly abide by the rules and regulations of the school.

The university campus is a place where students live together. It is best not to keep small animals privately, because some animals are important sources of infection or pathogen hosts in some people and animals. Once they are infected, they can easily spread to the human body.

Cats and puppies are not aware of environmental protection, and they may defecate at will in public places, which seriously pollutes students' learning environment and living environment, and at the same time, animal diseases may cause epidemics.

In fact, even if pets are groomed every day, they may still have parasites. These parasites may breed in people, things, wardrobes, beds and other places, posing a threat to the health of themselves and their roommates.
