Colleges Extend the Welcome Mat to Students' PetsAn increasing number of colleges are allowing students to bring their pets with them to school. After agreeing to some very strict rules, students can keep their cats, birds, dogs, and, in some cases, non-venemous snakes in their dorm rooms. Those colleges with designated dorms allowing pets believe that students who opt to bring their pet to school show greater responsibility and organization. Others worry that having a pet might keep those pet owners more isolated.
