First of all, pets are not allowed in general school dormitories. If you keep a pet secretly and keep some animals that everyone is afraid of, your roommate will definitely not agree. People who don't like small animals, no matter what you raise, won't like it. Why do you have to keep animals in the dormitory … you are not the only one living here. You'd better restrain all kinds of strange ideas ... If you really want to keep it, move out.
So I suggest that it is best not to keep pets in the dormitory. Pets are not allowed in the dormitory, and not all roommates like pets. Finally, if things are exposed, you will be punished by the school, and the loss will outweigh the gain. So it's better not to keep pets, let alone dangerous animals, and you can't keep them.
