Even though tons of colleges have animals as mascots, they may not be welcome inside dorm doors. I attended a university where nearly everyone lives on campus for all four years . . . and the housing is not pet-friendly. However, the year I lived in an apartment style unit, I had a friend who would sneak her family dog to stay on weekends, once found a kitten in the hallway, and even had a pal with a lil bird.Nowadays more and more institutions offer pet-friendly rooms – how was it like for you (and did you ever look for a loophole)?
