Yes, I think you could make it work. I too am a college student with 3 room mates, and I have 5 ferrets, but I've owned since I was in the 8th grade. Your room mates have to be on board, though. I'll help you pro and con it.
Cons:
-ferrets are expensive. When you first get one, it will be between $700-1500 for all their requirements.
-They are picky eaters. Their food must be high quality cat food or ferret food (http://www.mdferretpaws.org/care/food_treats.html) OR a whole prey diet.
-They need constant supervision or a VERY thorough "proofing" of your home, kind of like for a baby, except more anal because babies can't get into vents or couches or into refrigerators.
-They're obligate carnivores. No sweets, veggies, fruits, or dairy. ONLY meat. Btw, they can't have yogurt because ferrets are lactose intolerant as well... Sugary foods will give them cancer (insulinoma, look it up)
-Litter must be scooped once a day. If not, it may smell. It would be like letting dog or human poop set around otherwise. The smell is about the same.
-Must be nip-trained. Many kits bite HARD and if not taught otherwise, will continue to do so.
-Some ferrets are tough about litter training, but with consistency and patience it is very doable.
-If you want to free-roam, you'll need a LOT of litterboxes--one for about every corner. They must have low sides.
-It can be hard to find a vet that will treat sick ferrets, or even knows what he's talking about.
-Because they are bred at puppy-mill like facilities here in the US (Marshall Farms), they are prone to a genetic diseases like a tendency for cancer (adrenal, insulinoma, and lymphoma/lymphosarcoma especially).
-If they swallow something they shouldn't (which is very easily done), it usually costs between $500-1000 to remove. Surgeries for their later-life cancers usually cost about the same
-Need 4-6 hours of interactive playtime a day. If your house is not ferret-proofed EXTREMELY well, you'll have to watch him/her like a hawk the whole time.
Pros:
-They're a LOT of fun. Kind of like a cross between a cat and a puppy.
-Ferret winter coats are to die for, if they're healthy. So soft and shiny.
-Their bodies don't stink, contrary to popular belief. Over bathing usually causes that. No more than once every couple months, unless it gets really, really dirty.
-If kept healthy on a good diet and regular vet visists, can live up to 13 years old, but usually more like 7-10 years. Ferrets from breeders are usually healthier.
-If you free-roam, they're usually a lot cuddlier than ferrets kept in a cage most of the time.
-They "give kisses" like a dog, which I think is adorable.
-If treated properly, they will bond with you.
-They're a good conversation piece--not many people have ferrets or know much about them if they do (sad...)
-They can be walked on a leash, but will not be as well-trained on-leash as a dog.
-Can be kept in a cage when you're not there to supervise
-Usually get along well with people and other pets. My 5 love everyone, including my parents' cat and my American Foxhound.
They're a lot of hard work, so do your research before you commit to getting one. Best of luck!
