ABSTRACT

Although they were once widely involved in research, hamsters are now relatively uncommon research animals. Two main types of hamsters are seen in biomedical research: the Chinese (Cricetulus griseus) and the Syrian (Mesocricetus auratus). This chapter will address the Syrian exclusively, since it is by far the most numerous species in the laboratory, and is what most people think of when they think “hamster”. Natural history, ecology, and typical research contributions will be addressed, as well as hamster behavioral biology, including social, mating, and parental behaviors. Finally, behavioral management recommendations for the laboratory hamster, including optimal housing and care, are suggested.
