(EDIT: about the recommendation to get a basset hound, quoted the wrong frame somehow. Mea culpa.)
Nah, I disagree, unless you're going to be studying at home. Basset hounds are compulsive cuddlers, one of those breeds that lean into your leg while standing next to you. They need you to be around.
But if you have a cat, OP, and you live with pet-loving flatmates, your cat should be alright. You wouldn't be missing out on the dorm experience, i.m.o..
