Abstract: A wall-less animal containment system for non-flying animals. The containment system includes a lower enclosure (24) that defines a generally upward concavity from a center portion (44) to a rim (48) with a wall extending between the center portion (44) and the rim (48). The interior surfaces of the wall are sufficiently smooth to prevent the animals contained therein from gripping onto the wall and climbing out of the lower enclosure (25). A perch is (50",50') is located above the lower enclosure (24) to permit animals in the containment system to perch above the lower enclosure (24). A lower support (36, 120) extends from the lower enclosure (24) and spaces the perch (50", 50') above the lower enclosure (24). The lower support (36, 120) is located so as to be a distance away from the rim (48) of the lower enclosure (24) to prevent an animal from climbing from the support (36, 120) to the rim (48).
