I did it with two rats, a salamander, fish (those were allowed though), a turtle (short term for a friend), a hamster, & a rabbit.

So it is possible. But it can and can't be under different circumstances. I was supposed to have an assigned roommate but she ended up going to a different school so I had a room to myself, if I didn't I probably wouldn't have been able to do any of that lol. But look into schools where you can apply for single room dorm living, it's so nice because you can have all the fun on the floor and all, but then be alone when you want too.

And yes that's right they can't dig through your stuff unless they find a reason to (the example given to us was paraphernalia sitting out or alcohol bottles) And our cleaning people couldn't step onto the carpet area, we were also given schedules of when they would be there. So I turned my desk to where it was facing the door and put my hamster on the other side of it and I raised my bed up a few notches, made a curtain, and put my rabbit under there When I knew they were coming. I had a few people that knew about my pets, a few with depression issues and it helped them so much through the year to come chill with my animals, me included. So there is something in saying you feel like you can't live without them. But do remember if worse comes to worse you can of course.

Look into colleges close by to if you're really worried about it. Then you can just head home on the weekends and care for him, however if you're home every weekend you're missing some good parties haha. I would also recommend if you do decide to move forward, wait a week or two to get the feel of how your dorm floor works. You could also buy a small two snake rack system or make one, I've seen them for sale at some shows. That would be EXTREMELY easy to hide. No lights :p

That's all I can think of right now, best of luck (: remember everyone's experiences are different and yours will be too.
