First use completely blacked out containers so no one can see what's inside or out. Second label the container with the most boring thing you can think of that no other college kid could possibly even be remotely be curious to investigate while intoxicated/high/sober/etc. (Very important to think of a name which would contain something everyone would have to respect if they are decent human beings); "Lord of the Rings Collections" (unless your friends with a ton of fan boys/nerds a common series that is nerded out about should deter most) , "Photos of Mother" (That one would only work if it was common knowledge of dead family member), "Medical Enemas" (Would you want to touch someones medical enemas that were so delicate needed a thermostat/ proper humidity to be stored?), "Violin Container" (I'd recommend something like this because then you have an excuse into why you need proper humidity/heat for said container; "Oh violin get's out of tune if not properly kept") etc. Hide them in a place where no one would look unless they were being peeping toms. For example buy a large compartment dresser and put said container with your underwear. With hiding snakes everyone always forgets food DO NOT HIDE FROZEN THAWED RATS IT WILL GET FOUND AND HOW WOULD YOU POSSIBLY JUSTIFY THE HOBBY OF CAPTURING RATS AND SECRETLY FREEZING THEM (They will assume you killed the rats and put them in ziplock bags and for some reason KNOWINGLY hide them). Get live food from your local breeder it will be a pain in the large intestine but you chose to buy that snake and you chose to go into college knowing that having a secret snake wasn't allowed.

On my own advice nothing is a greater chick/friend deflector to college girls/guys (There are exceptions to every rule but it's safer to assume said person won't like snakes than to assume they do) than openly saying you own hundreds or multiple snakes; majority of the time they will look at you as if you just massacred a Vietnam village due to the common phobia of snakes in western society. Plus if your frozen rats get discovered you'll be known as the biggest creeper on the planet if no one finds the snake. This all depends on who you hangout with or what college you're at because different social classes tolerate/open to more uncommon ideas/hobbies.

This type of maintaining of snakes is completely short term and will give you a year to finally set your bearings in your dorm and then jump out of there into an apartment complex.
DO NOT get caught by roommates even if they opened your container labeled "Medical Enemas" they will use the snake as black mail or report you 67% of the time.
P.S i do not personally do this but it's fairly easy to hide something you need given the proper well thought out excuses if someone ever were to discover said container.
