Abstract: A small animal globular housing and exercise module including a main body which is formed by two hemispherical body pieces fabricated from a transparent thermoplastic material. A lid opening, large enough to accommodate a human hand, is formed in one of the body pieces and a lid removably closing the lid opening is provided. Ventilation openings of sufficient size and number to allow for air passage through the module are provided. A pair of through openings are formed opposite to each other and are positioned along and split by a division plane defining the two hemispheres for possible passage of small animals therethrough, each opening having an outwardly protruding portion. Annular connecting rings engage the protruding portions of each opening passage and hold the two body pieces together. A pair of bubble caps are engaged by a side of each annular ring opposite to a side engaging the protruding portions of the through openings.

Abstract: A small animal visual burrowing module which includes a main burrowing enclosure body having an interior space defined by opposite walls spaced a short distance apart. The burrowing enclosure body is formed by two symmetrical body pieces. The main burrowing enclosure body has an open bottom, with a wire grate mounted across the open bottom. Two generally horizontal intermediate floors are symmetrically formed in the body pieces. Each body piece including at least one laterally extended viewing window. Ventilation openings of sufficient size and number to allow for air passage through the module are provided. A plurality of through openings are provided in the walls of the enclosure body, for the passage of small animals therethrough, with each opening having an outwardly protruding portion.
