A cage structure consists of a roof member and base member each having a bore at each of its corners, and a series of wall members releasably securable together and to the roof and base members to form an enclosure. Each wall member also has a bore at each of its corners. Three way connectors or joints releasably connect the corners of the adjacent three members at each corner of the cage. Each three way connector has three arms which engage in the respective bores of the three members at that corner to secure the members together, so that a major part or all of the connector is concealed when the cage is assembled.
