the drawings one type of vivarium or terrarium with which this invention is concerned is illustrated in fig1 terrarium 2 as can be seen is fabricated so that it has a bottom or floor 4 a top panel 6 side panels 8 front panel 10 and a back panel 12 as can be seen each panel has four other panels attached to it one to each of its four edges thus front panel 10 has top panel 6 along its top edge side panels 8 along each side edge and bottom panel 4 attached along its bottom edge if these walls were squares the structure would be a cube since the walls are rectangular rather than square the terrarium is a parallelepiped an elongated cube in actual fabrication these edges are a framework for glass clear plastic or screen panels as is readily apparent in fig1 screens are in the sides and top and clear plastic or glass panels are in the front and back whereas a suitcase shaped terrarium is desirable a high narrow terrarium is preferred so that the creatures living in it have room to roam and play for terrariums then the top bottom and side rectangular panels will be long and narrow yielding a terrarium which is narrow from front to back but sufficiently high to allow for plant growth.
