Title: Positionable and expandable tube system having slotted tube segments

Abstract: A positionable and expandable tube system composed of snappingly engageable slotted tube segments for the construction of hamster, gerbil, or like pet tubes. Each tube segment consists of an upper and a lower truncated sphere connected at an annular intersection. The preferred embodiment incorporates an upper truncated sphere having a plurality of tapered slots delineating flexible arcuate portions which can be flexed inwardly upon contact with a lower truncated sphere of a succeeding tube segment to reduce the cross section of the upper truncated sphere to allow easily accomplished entry into the lower truncated sphere of a succeeding tube segment. The tube segments, when snappingly engaged, create frictionally positionable ball and socket joints.
