Abstract

Revolvable, hollow spheroid has a pair of tubes communicating with its interior 180.degree. apart. The free ends of the tubes may be closed with caps to prevent the animal from escaping. A housing mount rotatably mounts the spheroid and serves as an access opening for an animal of the rodent type. The animal may rotate the spheroid by running on its inner surface or by entering one of the tubes. The housing mount includes a fitting for connecting the spheroid to a tube communicating with an animal cage.
