Crowdsourcing Methods to Keep Strays Away

[hiro_shi]

Recently, it has come to my attention that there's been a sudden influx of strays in my room the mansion. With the guaranteed mess and trouble it'll cause, I'm in need of some ways to deter it from coming back. If not, then at the very least, I'd like to know how I could possibly contain its mischief. 

If you have any suggestions, please tell me. So far, my classmates have suggested I spray it with water. I've yet to try this but I will when it comes back.
