It should be easy to find on campus, because it won't be cheated by bad people. Call more when you go out. He knows your voice. Bring cat food and sprinkle some downstairs, because there are many dormitories, and cats may not find any buildings. The fifth floor is too high for them to smell. Find it several times, at different times. You can look for it at night when there are few people. Because cats are afraid of people, there may be too many people during the day, so they hide. Scissors solution is the last resort. The last time I lost my cat, I found it in the basement of the building in front of me. I got lost and hid in the basement. I called from door to door and finally got a response. I wanted to cry, but I found it. Don't give up, you will find it.
