A student has sued Grand Valley State University, charging that her rights are being violated by a ban on her keeping a guinea pig in her dormitory room for "emotional support," The Grand Rapids News  reported. The university normally bars all pets except non-predatory fish. Kendra Velzen, the student, says her pet offered her help in dealing with depression and a heart condition. After the story broke, the university told the News  that it had permitted the pet to stay, but that Velzen had rejected university requests that she agree not to take the guinea pig to class, to common areas, or to food service areas. The guinea pig has died since the dispute started. The litigation follows a suit against the University of Nebraska at Kearney  by a student who wanted to keep a dog in her room.
